Question

Please help me solve this. I don’t remember learning this

Answer 1

`D)\text{ d}`

Step-by-step explanation

let's remember some properties of the exponents and radicals

`\begin{gathered} a^{(1)/(m)}=\sqrt[m]{a} \\ a^{(n)/(m)}=\sqrt[m]{a^n} \\ a^m*a^n=a^(m+n) \end{gathered}`

so

Step 1

given

`√(d^2)`

hence, let's apply the rule

`√(d^2)=d^{(2)/(2)}=d^1=d`

therefore,the answer is

`D)\text{ d}`

I hope this helps you
