Question

Which expressions are equivalent to the one below? Check all that apply. ไ 21% 3x

Answer 1

we have the expression

`(21^x)/(3^(^x))`

so

`\begin{gathered} (21^x)/(3^x)=((3*7)^x)/(3^x)=7^x \\ \\ (21^(x))/(3^(x))=((21)/(3))^x \end{gathered}`

therefore

the answers are

options B, C and D
