Short Answer

Expert verified

0.2 raised to the power 2.

Value of given expression is $0.04$ .

Repeated multiplication is $0.2 \times 0.2$ .

Step by step solution

Step-1- Concept of exponents and power

Consider the expression, $x^{y}$ .

The expression can be written in word as “x raised to the power y”. Here, x is the base and, y is the exponent.

Step-2-Evaluating given expression

${(0.2)}^{2}$

In given expression, 0.2 is the base & 2 is the exponent.

So, it is written as 0.2 raised to the power 2.

Repeated multiplication is $0.2 \times 0.2$ .

On simplifying, it gives,

$\begin{matrix} {(0.2)}^{2} = 0.2 \times 0.2 \\ {(0.2)}^{2} = 0.04 \end{matrix}$

Step-3-Conclusion

Therefore, the value of given expression is $0.04$ .
