Math Problem Statement

Select the equivalent expression: (x^6 * x^4) / x^7

Solution

The expression given in the image is:

x6x4x7\frac{x^6 \cdot x^4}{x^7}

Let's simplify this step by step.

  1. Apply the multiplication rule of exponents: xaxb=xa+bx^a \cdot x^b = x^{a+b}. So,

x6x4=x6+4=x10x^6 \cdot x^4 = x^{6+4} = x^{10}

  1. Now, the expression becomes:

x10x7\frac{x^{10}}{x^7}

  1. Use the division rule of exponents: xaxb=xab\frac{x^a}{x^b} = x^{a-b}. So,

x10x7=x107=x3\frac{x^{10}}{x^7} = x^{10-7} = x^3

Therefore, the equivalent expression is x3x^3.

Among the answer choices, the correct option is x3x^3.
