Answer: 5x^-10 * -2x^4
To simplify this expression, we will multiply the coefficients (the numbers in front of the variables) and add the exponents of x.
5 * -2 = -10
-10x^(-10 + 4) = -10x^-6
So, the simplified expression is:
-10x^-6
2.-4x^2 * 3y^-5 * 2y^7 * x^-6
To simplify this expression, we will multiply the coefficients and add the exponents of x and y.
-4 * 3 * 2 = -24
-24x^2 * y^(-5 + 7) * x^(-6)
-24x^2 * y^2 * x^-6
-24x^(2 - 6) * y^2
-24x^-4 * y^2
So, the simplified expression is:
-24x^-4 * y^2
