Chapter 2: Q54. (page 66)

Evaluate the expression. (Lessons 1.2, 1.3)

25

Short Answer

Expert verified

The value of 25 after evaluating the power is 32.

Step by step solution

01

– Explanation of the exponent formula

ax→a is the base and x is exponent.

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

The expressionsaxthis means that a has been used as a factor x times

02

Find the base and power of 84 and evaluate

Example: Find the base and the power of 84 and evaluate the value.

Rule: ax→a is called base and x is power.

a = 8 and x = 4

Base = 8 and power = 4

Evaluate: 84  =8 · 8 · 8 · 8 =  4096

03

Evaluate the expression 25

Evaluate the value of 25

Rule: ax→a is called base and x is power.

a = 2 and x = 5

Base = 2 and power = 5

Evaluate: 25  =  2 · 2 · 2 · 2 · 2  =  32

The value of 25after evaluating the power is 32
