    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.

    you have to find the square root of 88.

    But the only answer choices are 44, 22 square root of 2, 2 square root 22, and 88..

    \[\sqrt{88}=\sqrt{4*22}=\sqrt{4}\sqrt{22}=2\sqrt{22}\]
