Question

PLEASE HELP ASAP

i understand the simplifying part, please thoroughly explain how to do excluded values correctly! tysm

Answer 1

`\\ \rm\Rrightarrow (XY)/(a^2+a^3)* (a+a^2)/(x^2y^2)`

`\\ \rm\Rrightarrow (xy(a+a^2))/(a^2+a^3(x^2y^2))`

`\\ \rm\Rrightarrow (axy+a^2xy)/(a^2x^2y^2+a^3x^2y^2)`

`\\ \rm\Rrightarrow (xy(a+a^2))/(x^2y^2(a^2+a^3))`

`\\ \rm\Rrightarrow (a+a^2)/(xy(a^3+a^2))`

`\\ \rm\Rrightarrow (a(a+1))/(xya^2(a+1))`

`\\ \rm\Rrightarrow (a)/(a^2xy)`

`\\ \rm\Rrightarrow (1)/(axy)`

Answer 2

`\qquad\qquad\huge\underline{{\sf Answer}}♨`

Let's solve ~

`\qquad \sf  \dashrightarrow \: \frac{xy}{ {a}^(2) + {a}^(3) } * \frac{a + {a}^(2) }{ {x}^(2) {y}^(2) }`

`\qquad \sf  \dashrightarrow \: \frac{xy}{ a({a}^{} + {a}^(2) )} * \frac{a + {a}^(2) }{xy( {x}^{} {y}^{} )}`

`\qquad \sf  \dashrightarrow \: \frac{ \cancel{xy}}{ a \cancel{({a}^{} + {a}^(2) )}} * \frac{ \cancel {a + {a}^(2)} }{xy \cancel{( {x}^{} {y}^{} )}}`

`\qquad \sf  \dashrightarrow \: (1)/(a) * (1)/(xy)`

`\qquad \sf  \dashrightarrow \: (1)/( axy)`
