Question

evaluate the expression.
(0.64 ÷ 3.2)² + 0.43
write your answer as an integer or a decimal. do not round.

Explanation:

Step1: Calculate the division inside the parentheses

First, we need to solve the division \(0.64\div3.2\).
\(0.64\div3.2 = 0.2\)

Step2: Square the result from Step1

Next, we square the result we got from the division. So we calculate \(0.2^{2}\).
\(0.2^{2}=0.2\times0.2 = 0.04\)

Step3: Add 0.43 to the result from Step2

Finally, we add \(0.43\) to the result of the square. So we calculate \(0.04 + 0.43\).
\(0.04+0.43=0.47\)

Answer:

\(0.47\)
