Question

125 125 A. O B. 25 C. 11.2 D. 5

Answer 1

Cube root

We want to find a number that multiplied three times by itself equals 125 in order to find

`\sqrt[3]{125}`

We know that

25 · 5 = 125

and

5 · 5 = 25

Then

`\begin{gathered} 5\cdot5\cdot5=125 \\ 5^3=125 \\ \end{gathered}`

Then

`\begin{gathered} \sqrt[3]{125}=\sqrt[3]{5^3} \\ \sqrt[3]{125}=5 \end{gathered}`

Answer: D. 5
