Chapter 4, Problem 13PSQ

To determine

To write the power in words and repeated multiplication & then evaluate the power. ${\left(0.2\right)}^2$

Answer to Problem 13PSQ

Words- 1.3 raise to the power 3

Repeated Multiplication- $0.2\times 0.2$

Evaluated-0.04

Explanation of Solution

Given information:

Expression ${\left(0.2\right)}^2$

Calculation:

To write the power in words- say it x raise to the power y- where x is the base and y is the exponent.

In expression ${\left(0.2\right)}^2$ , 0.2 is the base & 2 is the exponent. So it is written as 0.2 raise to the power 2.

For repeated multiplication, multiply the base ‘x’ , ‘y’ (exponent) times.

It will be written as $0.2\times 0.2$

To evaluate the expression, simply multiply. Hence,

  $0.2\times 0.2=0.04$
