Question

a)If m=-2,n=2 and p=3,find the value of the expression(4p-mn) (pn-pm)

Answer 1

Answer:

M=-2

N=2

P=3

put value in the expression

(4p-mn) (pn-pm)

(4×3-(-4)) (3×2-(-6))

(12+4) (6+6)

(16) (12)

= 192

Answer 2

Answer:

Answer

Given expression is,

2mn4−15m2n+p,

Substituting m=1, n=2 and p=−3, we get

   2mn4−15m2n+p

=2(1)(2)4−15(1)2(2)+(−3)=32−30−3=−1
