Question

Rewrite the indicated real nth root(s) of a in radical form
Algebra

1) n=3,a=27

2) n=4,a=16

3) n=6,a=64

4) n=5,a=243

Answer 1

Answer:

$\sqrt[n]{a}$

1. $\sqrt[3]{27}$ = $\sqrt[3]{3^3}$ = 3

2. $\sqrt[4]{16}$ = $\sqrt[4]{2^4}$ = 2

3. $\sqrt[6]{64}$ = $\sqrt[6]{2^6}$ = 2

4. $\sqrt[5]{243}$ = $\sqrt[5]{3^5}$ =3

Hope that helps!
