The third power of sqrt of 5b^9. Can someone point out the steps for solving this problem. Thanks for your help in advance.

  • algebra -

    change b^9 to b^8*b

    sqrt (5b^8*b)=b^4 sqrt5b

    now cube all that.

    b^12 (5b)sqrt5b

  • algebra -

    [sqrt(5 b^9]^3 = [(5 b^9)^(1/2)]^3
    = 5^(3/2) * b^(9/2)
    = 11.18034.. b^(9/2)
