What You Will Learn in RS Aggarwal Class 9 Exercise 1F

In RS Aggarwal Class 9 Exercise 1F, you will practice five main rules about how to work with numbers raised to powers. These rules include:

1. Adding exponents when you multiply like bases
2. Subtracting exponents when you divide like bases
3. Multiplying exponents when you raise a power to another power
4. Understanding that any nonzero number raised to the zero power equals one
5. Converting a negative exponent into a fraction

These five rules are the heart of RS Aggarwal Class 9 Exercise 1F. Mastering them will make advanced algebra easier and build confidence for exams.

Core Exponent Rules in Plain English

Before we jump into examples, let us review each rule from RS Aggarwal Class 9 Exercise 1F using only words:

Rule One – Multiplying Like Bases:

When you multiply two expressions that have the same base, you keep the base and add the exponent numbers together.

Rule Two – Dividing Like Bases:

When you divide one expression by another that shares the same base, you keep the base and subtract the exponent in the bottom from the exponent in the top.

Rule Three – Power of a Power:

When you raise an expression that already has an exponent to another exponent, you keep the base and multiply the two exponent numbers.

Rule Four – Zero Exponent:

Any number other than zero, when raised to the zero power, always equals one.

Rule Five – Negative Exponent:

A negative exponent means you take the reciprocal of the base raised to the corresponding positive exponent. These are the five rules you will use repeatedly in RS Aggarwal Class 9 Exercise 1F problems.

Step-by-Step Solutions to Representative Problems

Below are clear English explanations for sample problems you will find in RS Aggarwal Class 9 Exercise 1F.

Example One: Multiplying Like Bases

Problem Statement: Multiply two expressions that both have base x, one raised to the third power and the other raised to the fifth power.

Plain English Solution:

First, notice that both expressions have the same base, x. According to our first rule, when you multiply like bases you add the exponent numbers. So you add three and five to get eight. The result is the base x raised to the eighth power.

Example Two: Dividing Like Bases

Problem Statement: Divide one expression by another when both expressions have base two, one raised to the sixth power divided by the same base raised to the second power.

Plain English Solution:

Both expressions share the base two, so you use the second rule. You subtract the exponent in the denominator from the exponent in the numerator. Six minus two equals four. So the answer is two raised to the fourth power.

Example Three: Power of a Power

Problem Statement: Take an expression that has base y raised to the second power and then raise that entire expression to the third power.

Plain English Solution:

You use the third rule. You multiply the two exponent numbers together. Two times three equals six. The result is base y raised to the sixth power.

Example Four: Zero Exponent

Problem Statement: Find the value of five raised to the zero power.

Plain English Solution:

According to the fourth rule, any number other than zero raised to the zero power equals one. Therefore, five raised to the zero power equals one.

Example Five: Negative Exponent

Problem Statement: Express three raised to the negative second power as a fraction.

Plain English Solution:

The fifth rule tells us that a negative exponent means you take the reciprocal of the base raised to the positive exponent. So three raised to the negative second power becomes one over three raised to the second power, which equals one over nine.

Common Mistakes in RS Aggarwal Class 9 Exercise 1F

While practicing RS Aggarwal Class 9 Exercise 1F, watch out for these pitfalls:

• Reversing Subtraction: In fixed base division problems, be careful to subtract the bottom exponent from the top exponent, not the other way around.
• Forgetting to Multiply Exponents: When you raise an exponent expression to another exponent, some students accidentally add instead of multiply.
• Misapplying the Zero Exponent Rule: Never treat something raised to the zero power as zero; it always simplifies to one.
• Ignoring the Reciprocal for Negative Exponents: Always remember that a negative exponent flips the base to its reciprocal form.

By staying alert to these errors, you can solve RS Aggarwal Class 9 Exercise 1F with greater accuracy.
