Question

( x^5 y^-3 / 5x^9) ^-2

i cant figure this out ;( i need help

Answer 1

The exponent of -2 must be multiplied into each exponent... So the numerator would be x^-10y^6
Once you have multiplied the -2 into the denominator exponents, then when the bases are the same combine the exponents : )

Answer 2

would the answer be 10^28 y^6 / 25

Answer 3

(x^5y^-3/5x^9)^-2.
(x^-4y^-3/5)^-2,
x^8y^6/5^-2,
x^8y^6(5^2) = 25x^8y^6.
