Chapter 1: Q7. (page 12)

Evaluate the expression k² when k = 6.
k²when k = 6

Short Answer

Expert verified

The value of $k^{2}$ after evaluating the power is 36 when k = 6.

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 power of 34 and evaluate

Example: Find the base and the power of $3^{4}$ and evaluate the value.

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

a = 3 and x = 4

Base = 3 and power = 4

Evaluate: $3^{4} = 3 \cdot 3 \cdot 3 \cdot 3 = 81$

Evaluate the expression k2 when k = 6

Evaluate the expression $k^{2}$ when $k = 6$ .

According to the exponent rule:

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

a = k and x = 2

In repeated multiplication: $k^{2} = k \cdot k$

When k = 6: $k^{2} = k \cdot k = 6 \cdot 6 = 36$

The value of $k^{2}$ after evaluating the power is 36
