(9a^3b^4-12a^2b^5+6ab^7)/(6a^2b^3)

Answer 1

( 9 a ^ 3 b ^ 4 - 12 a ^ 2 b ^ 5 + 6 a b ^ 7) / ( 6 a ^ 2 b ^3 ) =

3 * a * b ^ 3 * ( 3 a ^ 2 * b - 4 a * b ^ 2 + 2 b ^ 4 ) / [ 3 * a * b ^ 3 * ( 2 a ) ] =

( 3 a ^ 2 b - 4 a b ^ 2 + 2 b ^ 4 ) / 20

Answer 2

Sorry last row :

= ( 3 a ^ 2 b - 4 a b ^ 2 + 2 b ^ 4 ) / 2 a
