Question 355804
Hi,
*Note: sometimes the harder it gets the easier it is!
.
Laws of exponent that will be helpful here:
{{{(a^p)^q = a^(p*q)}}} and {{{(a^m)(a^n) =a^(m+n)}}}
.
{{{(-3xy^3)^4 = (-1^1*3^1*x^1*y^3)^4 = (-1^4*3^4*x^4*y^12)= 81*x^4*y^12}}}
.
{{{(-mn^8)^3 = (-1^1*m^1*n^8)^3 = -1^3*m^3n^24
= -m^3n*24 }}}
.
{{{(-2x^(2y))^3*(5xy^3)^2 = (-2)^3*x^(6y) * (5^2*x^2y^6) = -200 x^(6y +2)*y^6}}}
.
{{{(4x^5y^2)/(-2*x^3*y^2)^2 = (4*x^5*y^2)/4x^6y^6)}}} = x^(-1) * y^(-4)
