Which expression is equivalent to (5x−5y3) −2?

The expression is equivalent to (5x−5y3) −2? is 1/5x^10y^-6
The expression is given as:
Expression = (5x−5y3) −2?
Rewrite properly as:
Expression = (5x^−5 y^3)^−2
Remove the bracket.
So, we have:
Expression = 5^-1 * x^(−5 * -2) y^(3*−2)
Evaluate the product of the exponents
So, we have:
Expression = 1/5 * x^10 * y^-6
Evaluate the products
So, we have:
Expression = 1/5x^10y^-6
Hence, the expression is equivalent to (5x−5y3) −2? is 1/5x^10y^-6
