Answer 1

2/3 * 9х/4 = 1 * 3х/2 = 1,5 х

(х+2)/1 * х/(3х+6)= (х+2)/1 * х/3(х+2)= 1 * х/3 = х/3

а6/4в2

(у2-4)/3у * 3у2/(у2-2у)= (у-2)(у+2)/3у * 3у2 / у(у-2)= (у+2) / 3у * 3у2 / у= (3у3+ 6у2)/3у2= 3у2(у+2)/3у2= у+2

Answer 2

2/3x³ * 9x⁴/4=3x/2

(x+2)*x/3x+6=x/3

(-a³/2b)²=a⁶/4b²

(y-2)(y+2)/3y * 3y²/y(y-2)=y+2
