Question

Can you simplify this and give me the simplified answer and the domain?

Answer 1

the given expression is,

`-(25x^3y^3)/(14a^2b)*(-(21ab)/(10x^2y))`

now we solve it,

`=(25x^3y^3)/(10x^2y)*(21ab)/(14a^2b)`
`=(5x^(3-2)y^(3-1))/(2)*(21)/(14a^(2-1))`
`=(105xy^2)/(28a)`

thus,, the answer is 105xy^2 / 28a
