Question 116947
1)
You can't cancel anything here, just multiply the numerators together and the denominators, remember to add exponents of like terms when you multiply
{{{16x^2/y^4}}}*{{{5x^2/y^2}}} = {{{80x^4/y^6}}}
:
2)
Do the same with this one:
{{{6x^5y^3/(5z^3)}}}*{{{6x^4/(5yz^4)}}} = {{{36x^9y^3/25yz^7}}}
;
Did this help? Any questions?
