Question

Find the value of 3√x +7 if x = 25

Answer 1

Given the expression

`\begin{gathered} 3\sqrt[]{x}+7 \\ \end{gathered}`

Given that x = 25

Substitute 25 for x into the expression above

`\begin{gathered} \text{Where x = 25} \\ 3\sqrt[]{x}+7=3\sqrt[]{25}+7 \\ =3\sqrt[]{25}+7=3(5)+7 \\ =3(5)+7=15+7 \\ =15+7=22 \end{gathered}`

Hence, the answer is 22
