you cross multiply, the 8 with the 11 and the x combine like terms. you have to get rid of the exponent by applying the square root.

I know but in my problem also, how would you multiply two variables if they're not numbers/

So would the answer be either be 44 or 88? @completeidiot @meylispena ?
anonymous
  • anonymous
you have to find the square root of 88.
anonymous
  • anonymous
But the only answer choices are 44, 22 square root of 2, 2 square root 22, and 88..
anonymous
  • anonymous
\[\sqrt{88}=\sqrt{4*22}=\sqrt{4}\sqrt{22}=2\sqrt{22}\]
