Express each of the following prducts as a monomials and verify the result in each case for x=1:
Evaluate when x=1 and y=0.5
3.2 × 2.1 × x6 × x2 × y3 × y2
= 6.72 × x8 × y5
= 6.72x8y5
Verify:
When x = 1 and y = 0.5
R.H.S = 6.72x3y5
= 6.72 × 18 × 0.55
= 0.21
L.H.S = 3.2 × 16 × (-.5)3 × 2.1 × 12 × 0.52
= 0.21
Therefore,
L.H.S = R.H.S
