Question 202539
Simplify:
1. {{{((9a^3)/(10b^4))^-2 = ((10b^4)/(9a^3))^2}}}={{{highlight((100b^8)/(81a^6))}}}
2. {{{(6x^5y^2z^-4)(4x^-2y^4z^-1)}}} For each variable (x, y, and z), multiply their coefficients and add their exponents.
{{{24x^3y^6z^-5}}} Now make the z-exponent positive by moving it to the denominator.
{{{highlight((24x^3y^6)/z^5)}}}
3. {{{(u^5z^8)/(z^-5u^-4)}}} For each variable (u and z) subtract their exponents.
{{{(u^(5-(-5))z^(8-(-4)))}}} Simplify.
{{{highlight(u^10z^12)}}}
