Question

If r^n=a , then which of the following are true statements?

Check all that apply.
n1/r = a

n√a = r

a1/n = r

ar = n

Answer 1

I guessed n√a = r and a1/n = r ...

Answer 2

\[r^n=a~~~~~~->~~~~~~~~~~~a=\sqrt[n]{r}\]

Answer 3

what does that even mean? I'm so confused.

Answer 4

\[r=a ^{\frac{ 1 }{n }}\]
\[or`r=\sqrt[n]{a}\]

Answer 5

so b and c?

Answer 6

i don't think it is b
\[\because~n \sqrt{a}=n*a ^{\frac{ 1 }{2 }}~and~ \sqrt[n]{a} =a ^{\frac{ 1 }{ n }}\]

Answer 7

yeah I don't understand what you just wrote

Answer 8

if it is written outside sqrt just as\[n \sqrt{a}~then~\it~is~different~\to~\sqrt[n]{a }\]
\[n \sqrt{a}\neq \sqrt[n]{a}\]
