you add both of the exponents and then solve. x4•x7= x11
you subtract them both. y8/y4=y4
you put it under 1 in a fraction

To multiply two powers with the same base what do you do with the exponents? You add them together.
x4 • x7= x11

To didvide two powers with the same base what do you do with the exponents? You subtract them.
y8/y4=y4

How do you change a number with a negative exponents to a positive exponent? You make it as a fraction with 1 as the numerator.
