Math Problem Statement

(25)^{1/2} + (36)^{1/2} - (27)^{1/3} divided by (125)^{2/3}

Solution

The expression given in the image is:

(25)12+(36)12(27)13(125)23\frac{(25)^{\frac{1}{2}} + (36)^{\frac{1}{2}} - (27)^{\frac{1}{3}}}{(125)^{\frac{2}{3}}}

Step-by-step solution:

  1. Simplify the terms with fractional exponents:

    • (25)12(25)^{\frac{1}{2}} = 25=5\sqrt{25} = 5
    • (36)12(36)^{\frac{1}{2}} = 36=6\sqrt{36} = 6
    • (27)13(27)^{\frac{1}{3}} = 273=3\sqrt[3]{27} = 3
    • (125)23(125)^{\frac{2}{3}} = (1253)2=52=25\left(\sqrt[3]{125}\right)^2 = 5^2 = 25
  2. Substitute these values back into the expression:

5+6325\frac{5 + 6 - 3}{25}

  1. Simplify the numerator:

5+63=85 + 6 - 3 = 8

  1. Final expression:

825\frac{8}{25}

So, the value of the entire expression is:

825\boxed{\frac{8}{25}}
