Math Problem Statement

(5x^2/3 y^-1/2)(2x^2y^-3

Solution

To simplify the given expression:

(5x23y12)(2x2y3)\left(\frac{5x^{\frac{2}{3}}}{y^{\frac{1}{2}}}\right)(2x^2y^{-3})

Step 1: Combine constants and separate variables

The expression can be written as:

(52)(x23x2)(1y12y3)(5 \cdot 2) \cdot \left(x^{\frac{2}{3}} \cdot x^2\right) \cdot \left(\frac{1}{y^{\frac{1}{2}}} \cdot y^{-3}\right)

This simplifies the constants and separates the powers of xx and yy.

Step 2: Simplify the constants

52=105 \cdot 2 = 10

Step 3: Simplify the powers of xx

Using the rule of exponents aman=am+na^m \cdot a^n = a^{m+n}:

x23x2=x23+2=x23+63=x83x^{\frac{2}{3}} \cdot x^2 = x^{\frac{2}{3} + 2} = x^{\frac{2}{3} + \frac{6}{3}} = x^{\frac{8}{3}}

Step 4: Simplify the powers of yy

Using the same rule of exponents:

1y12y3=y123=y1262=y72\frac{1}{y^{\frac{1}{2}}} \cdot y^{-3} = y^{-\frac{1}{2} - 3} = y^{-\frac{1}{2} - \frac{6}{2}} = y^{-\frac{7}{2}}

Step 5: Combine the results

Now, putting everything together:

10x83y7210 \cdot x^{\frac{8}{3}} \cdot y^{-\frac{7}{2}}

This can be rewritten for clarity as:

10x83y72\boxed{\frac{10x^{\frac{8}{3}}}{y^{\frac{7}{2}}}}
