Question

`\sqrt[]64`write the exact and approximate value for radical when appropriate. when rounding, round to the nearest 10th place

Answer 1

start by doing the descomposition of the number

meaning that it could be written as

`\begin{gathered} \sqrt[]{64}=\sqrt[]{2^2\cdot2^2\cdot2^2} \\ \sqrt[]{64}=2\cdot2\cdot2 \\ \sqrt[]{64}=8 \end{gathered}`
