Chapter 1: Q7. (page 10)

Evaluate the expression when m = 3.
m⁴

Short Answer

Expert verified

The value of $m^{4}$ after evaluating the power is 81 when m = 3

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

Write the product 5 · 5 · 5 · 5 in exponent.

Example: Write the product $5 \cdot 5 \cdot 5 \cdot 5$ in exponent.

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

For: $5 \cdot 5 \cdot 5 \cdot 5$ :the base a = 5 and multiplied by 4 times.

In repeated multiplication: $5 \cdot 5 \cdot 5 \cdot 5$ in exponent form $5^{4}$

Evaluate the expression m4 when m = 3

Evaluate the expression $m^{4}$ whenm = 3.

According to the exponent rule:

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

a = m and x = 3

In repeated multiplication: $m^{4} = m \cdot m \cdot m \cdot m$

When m = 3: $m^{4} = m \cdot m \cdot m \cdot m = 3 \cdot 3 \cdot 3 \cdot 3 = 81$

The value of $m^{4}$ after evaluating the power is 81.
