Question

Simplify the expression (5x^4y^-3)^-2 NEED HELP ASAP

Answer 1

The simplified version of (5x^4y^-3)^-2 would be y^6/25x^8 (this is a fraction)

Hope this helps :)

Answer 2

For this case we must simplify the following expression:

`(5x ^ 4 * y ^ {-3}) ^ {-2}`

By definition of power properties we have:

`a ^ {-1} = \frac {1} {a ^ 1}`

So:

`(5x ^ 4 * y ^ {-3}) ^ {- 2} =\\(5x ^ 4 * \frac {1} {y ^ 3}) ^ {- 2} =\\\frac {1} {(\frac {5x ^ 4} {y ^ 3}) ^ 2} =\\\frac {y ^ 6} {25x ^ 8}`

Answer:

`\frac {y ^ 6} {25x ^ 8}`
