The expression (x^-8) (x^3) is equivalent to the expression x^n. what is the value of n?

mash [69]

Answer:

n=-5

Step-by-step explanation:

You must multiply $x^{-8}*x^{3}$ . The laws of exponents state that when multiplying exponents of the same base, you can just add the exponents and raise the base to the sum of the exponents. So, $x^{-8}*x^{3}=x^{(-8+3)}=x^{-5}$ . Since our end product is $x^{-5}$ , n is equal to -5.
