Question

Give Me Answer of No.10
With Process

Answer 1

Answer:

We have to find the product of the expression in order to express it as a monomial.

Now, We have (−xy3)×(yx3)×(xy)

=[(−x)×x3×x]×(y3×y×y)

=−x(1+3+1)×y3+1+1[∵aman=am+n]

=−x5y5

A=5,B=5

A+B=5+5=10

Verification for x=1,y=2:

LHS=(−xy3)×(yx3)×(xy)

=−(1)(2)3×(2)(1)3×(1)(2)

=−(8)×2×2

=−32

RHS=−x5y5

=−(1)5(2)5

=−32

∴ LHS=RHS

Hence verified.
