Question

I always get terribly confused on these, please show work?

Answer 1

I'll try my best to explain this.

First off, and equilateral triangle is just a triangle with 3 equal sides.

For the

`\sqrt[m]{n}`
You just plug in the numbers you're given (m=2 and n=121) So your equation would look like this

`\sqrt[2]{121}`
Which means the square root of 121. So really the question is simply asking for

`√(121)`
Your answer would be 11.

Answer 2

You are finding the square root of 121
*the answer is 11*
because if you times 11 by its self you get 121
