Question

1. Simplify the radical expression.
-4^√16x^8
Please help I don’t know which one.

Answer 1

`\bf \implies \large{ - 2x}^(2) \\`

Explanation:

`\bf \longrightarrow - 4 \sqrt{16 {x}^(8) } \\ \\\bf \longrightarrow - { ({2}^(4) {x}^(8)) } ^{ (1)/(4) } \\ \\\bf \longrightarrow ( - 2x)^{ \frac{1}{ \cancel{4}}1 * \cancel{ 8}2 } \\ \\\bf \longrightarrow \boxed{- 2x^(2)} \: ans.`
