Question 635405
<pre>
{{{(2x^2*y^(-3) / 3x^5y^2 ) ^(-2)}}}

Give the 2 and the 3 exponents of 1

{{{(2^1x^2*y^(-3) / 3^1x^5y^2 ) ^(-2)}}}

Multiply all 6 exponents inside the parentheses,
top and bottom, by the exponent outside the
parentheses, -2.

{{{2^(-2)x^(-4)*y^6 / 3^(-2)x^(-10)y^(-4) }}}

Move all the factors with negative exponents across
the fraction bar and change their exponents to positive:

{{{3^2x^10y^6y^4 /(2^2x^4) }}}

Add the exponents of the y's in the top.
Subtract the exponents of the x's
Write 3² as 9 and 2² as 4

{{{9x^6y^10 /4 }}}
