Question

If A=(28x5y4​ / 4
x​2y2),
B=(18 x4y3 / 3 x y),
C=( 24 x8y6 / 8
x5y4) Then (A+B+C)-(A-B+C)=

We have,A=28x5y44x2y2=7x3y2B=18x4y33xy=6x3y2C=24x8y68x5y4=3x3y2Now,A+B+C-A-B+C=A+B+C-A+B-C=2B=2×6x3y2=12x3y2

If A=(28x5y4​ / 4 x​2y2), B=(18 x4y3 / 3 x y), C=( 24 x8y6 / 8 x5y4) Then (A+B+C)-(A-B+C)=
