Step-by-Step Solution

To solve the problem of reducing the expression (x3)2×y5y3\frac{\left(x^3\right)^2 \times y^5}{y^3}, we'll follow these steps:

  • Step 1: Simplify (x3)2\left(x^3\right)^2 using the power of a power rule.

  • Step 2: Simplify the expression using the division rule for y5y^5 divided by y3y^3.

Let's execute these steps:

Step 1: Apply the power of a power rule to (x3)2\left(x^3\right)^2.

According to the power of a power rule, (xm)n=xmn(x^m)^n = x^{m \cdot n}.

So, (x3)2=x32=x6\left(x^3\right)^2 = x^{3 \cdot 2} = x^6.

Step 2: Simplify the division of exponents for the yy variable.

The expression now looks like x6×y5y3\frac{x^6 \times y^5}{y^3}.

Using the division rule for exponents, ym/yn=ymny^m / y^n = y^{m-n}, we get:

y5/y3=y53=y2y^5 / y^3 = y^{5-3} = y^2.

Final Expression: Combining the results from Step 1 and Step 2, we obtain:

x6×y2x^6 \times y^2.

Therefore, the solution to the problem is x6×y2x^6 \times y^2.

Answer

x6×y2 x^6\times y^2
