lol apparently Jen also had the same question

Question

2(3^(2^-1)-1)^-1

I do not understand how to do this one either

Answer 1

See answer to Jen's first question.

Answer 2

2(3^(2^-1)-1)^-1
work you way out from the inside
= 2(3^(1/2)-1)^-1
= 2(√3 -1 )^-1
= 2/(√3 - 1)
= 2/(√3 - 1)*(√3 + 1)/(√3 + 1)
= 2(√3 + 1)(3-1)
= √3 + 1
or 2.732...

Answer 3

Didn't realize that MathMate already answered the same question for Jen

Good to know that we got the same answer and Google also concurred
