Q23 of 116 Page 6

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
