Question

Carlos thinks that
`√(8)`is rational because
`{2}^(8) = 8`Is Carlos correct that
`√(8)`is a rational number, and why?

Answer 1

`\sqrt[]{8}`

and we can represent 8 as

`2^3`

then

`\begin{gathered} \sqrt[]{2^3} \\ \end{gathered}`

simplify

`2\sqrt[]{2}`

we cant simplify root of 2, then is an irrational number necause 8 is not a square square

the right option is B
