Math Problem Statement

Simplify the expression: (x/y^2)^5 * (x^2y^3/z^2)^3

Solution

The expression in the image can be interpreted and simplified as follows:

(xy2)5×(x2y3z2)3\left(\frac{x}{y^2}\right)^5 \times \left(\frac{x^2y^3}{z^2}\right)^3

Step 1: Apply the power to each term inside the parentheses.

  1. For the first term (xy2)5\left(\frac{x}{y^2}\right)^5: x5y10\frac{x^5}{y^{10}}

  2. For the second term (x2y3z2)3\left(\frac{x^2y^3}{z^2}\right)^3: (x2)3(y3)3(z2)3=x6y9z6\frac{(x^2)^3(y^3)^3}{(z^2)^3} = \frac{x^6 y^9}{z^6}

Step 2: Multiply the simplified terms together.

x5y10×x6y9z6\frac{x^5}{y^{10}} \times \frac{x^6 y^9}{z^6}

Multiply the numerators together and the denominators together:

x5+6y9y10z6=x11y9y10z6\frac{x^{5+6} y^9}{y^{10} z^6} = \frac{x^{11} y^9}{y^{10} z^6}

Step 3: Simplify the expression by canceling common terms.

The yy terms in the numerator and denominator can be simplified:

x11y109z6=x11yz6\frac{x^{11}}{y^{10-9} z^6} = \frac{x^{11}}{y z^6}

Final Simplified Expression:

x11yz6\frac{x^{11}}{yz^6}
