x squared equals 922. The square root is a decimal which I can't use.
So I have to simplify it to a radical...which I don't understand how to do.

  • If you need to siplify that radical, you should try to put all the numbers as product of prime factors.

    922 = 2*461

    2 and 461 are prime numbers. Then the transformation of the square root is √(922) = √(2*461) = (√2)(√461)

    So you can use that in any expression to try to simpliy with other numbers whose prime factors include 2 and 461.
