Question

Multiply 2/3x³y³ by (3x-15y) and verify the result for x= 2 y= -1 proper way​

Answer 1

Answer:

2/3​x3y3×(3x−15y)

=32​x3y3⋅3x−32​x3y3⋅15y

=2x4y3−10x3y4

Now, for x=2,y=−1, we have

L.H.S.-

2/3​x3y3×(3x−15y)

=2/3​(2)3(−1)3×(3⋅2−15⋅(−1))

=2/3​⋅8⋅(−1)×(6+15)

=(−316​)×21

=−112

R.H.S.-

2x4y3−10x3y4

=2(2)4(−1)3−10(2)3(−1)4

=2⋅16⋅(−1)−10⋅8⋅1

=−32−80

=−112

∵ L.H.S. = R.H.S.

Hence verified.
