  1. Simplify:
    0.0347 × 0.0347 × 0.0347 + (0.9653)3
    (0.0347)2 − (0.0347)(0.09653) + (0.9653)2
    1. 0.9306
    2. 1.0009
    3. 1.0050
    4. 1
Correct Option: D

Let 0.0347 = a
and, 0.9653 = b

∴  Expression =
a3 + b3
a2 − ab + b2

=
(a + b)(a2 − ab + b2)
 = a + b
a2 − ab + b2

= 0.0347 + 0.9653 = 1
