Which expression is equivalent to {40x^{-3}y^{5} {8x^{-2}y^{-2}}

Answer 1

To find the equivalent expression, we can multiply the two terms together:

(40x^(-3)y^5) * (8x^(-2)y^(-2))

When multiplying terms with the same base, we add the exponents:

40 * 8 * x^(-3 + -2) * y^(5 + -2)

Simplifying the exponents and the multiplication:

320 * x^(-5) * y^(3)

Therefore, the equivalent expression is 320x^(-5)y^(3).
