which exponent rules would be used to simplify this expression? 2x^(5)*12x^(-4)
a. the quotient rule to subtract 2-12=-10. you would also subtract the exponents to get 5-4=1 for the power of x
b. the power to power rule since you have two different exponents on the x, so the new exponent would be -20. also you would add 2 and 12 using the product rule for exponents
c. the product exponent rule to add 5+-4 to get an exponent of 1 on the x you would also multiply 2x12 since they are coefficients
d. the negative exponent rule to get 5-(-4) =9 for the power of x and then multiply 2x12=24 for the coefficient
