Chapter 1: Q3. (page 12)

Write the power in words and as a repeated multiplication. Then evaluate the power:
12²

Short Answer

Expert verified

The power is two and in repeated multiplication: $12 \cdot 12$ and $12^{2}$ = 144

Step by step solution

– Explanation of the exponent formula

$a^{x} \to$ a is the base and x is exponent.

The power is the result of repeated multiplication of the same factor.

The expressionsa^xthis means that a has been used as a factor x times

Find the base and exponent of 27 and evaluate

Example: Find the base and the exponent of 2⁷

Rule: $a^{x} \to$ a is called base and x is power.

a = 2 and x = 7

Base = 2 and power = 7

In repeated multiplication: $2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2$

Evaluate: $2^{7} = 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 \cdot 2 = 128$

Write the power in words and as a repeated multiplication and evaluate the power 122

Write the power in words and as a repeated multiplication. Then evaluate the power $12^{2}$ .

According to the exponent rule:

$a^{x} \to$ a is called base and x is power.

a = 12 and x = 2

Base = 12 and power = Two

In repeated multiplication:

12 \cdot 12

Evaluate: $12^{2}$ = $12 \cdot 12$ = 144
