Chapter 1.2, Problem 30E

To determine

To calculate: The value of $n^2$ .

Answer to Problem 30E

When $n=7,n^2=49$ .

When, $n=0.4,n^2=0.16$ .

Explanation of Solution

Given information:The value of $n=7$ or $n=0.4$ .

Calculation:

When value of $n$ is $7$ , $n^2$ is calculated by multiplying $7$ twice.

  $7\cdot 7=\underset{\_}{49}$

When value of $n$ is $0.4$ , $n^2$ is calculated by multiplying $0.4$ twice.

$(0.4)\cdot (0.4)=\underset{\_}{0.16}$ .
