Question

What is the value of x? Round your answer to the nearest tenth.

x2 = 86

±

Answer 1

I'm assuming that you mean x^2 (x squared), so correct me if I am wrong.

So, to get "x" by itself, you need to square root both sides to do this. This will produce x = 9.27, in which, rounded to the nearest tenth, x approximately = 9.3.
