Don't use calculated just use your mind.I giving you a clue,its answer is less than 2.

Read Solution (Total 4)

(a^3+b^3) = (a+b)[a^2-ab+b^2]
(a+b) = (a^3+b^3)/[a^2-ab+b^2]
Given expression is in the form of above formula
[ 0.0347x0.0347x0.0347+(0.9653)³ ] /(0.0347)² - 0.0347x0.9653 + (0.9653)² =>(0.0347+0.9653]
= 1.0000

(a^3+b^3) = (a+b)[a^2-ab+b^2]
so
[ 0.0347x0.0347x0.0347+(0.9653)³ ] /(0.0347)² - 0.0347x0.9653 + (0.9653)² =>(0.0347+0.9653]
= 1.0000

ans=1.3
by using formula (a+b)3=(a+b)(a2-ab+b2)
we can write the given question as follows
[(0.0347)^3+(0.9653)^3]/(0.0347)^2-0.0347x0.9653+(0.9653)^2
=>0.0347+0.09653=1.3
