Question

this spiral review quiz covers key concepts from unit 1 on the real number system and unit attempts to complete it, and your highest score will be recorded. number of attempts: 2 time limit: unlimited question 3 find the value of the expression. $sqrt{25}(sqrt{2^{3}+1}+3.7)=$

Explanation:

Step1: Calculate inner - square root value

First, calculate $2^{3}=8$, then $\sqrt{2^{3}+1}=\sqrt{8 + 1}=\sqrt{9}=3$.

Step2: Calculate the sum inside parentheses

Add the result of the square - root to 3.7: $3+3.7 = 6.7$.

Step3: Calculate the outer - square root value

We know that $\sqrt{25}=5$.

Step4: Multiply the two values

Multiply 5 by 6.7: $5\times6.7=33.5$.

Answer:

$33.5$
