Question

Prove that : (0.96*0.96*0.96+0.04*0.04*0.04)/0.96*0.96-0.96*0.04+0.04*0.04=1

Answer 1

$= \frac{0.96 \times 0.96 \times 0.96 + 0.04 \times 0.04 \times 0.04}{0.96 \times 0.96 - 0.96 \times 0.04 + 0.04 \times 0.04} \\ = \frac{0.8848 }{0.8848} \\ = 1$
Hence Proved

Answer 2

Answer:

(0.96)^3+(0.04)^3/(0.96)^2-(0.96*0.04)+(0.04)^2

0.884736+0.000064/0.9216-0.0384+0.00016

0.8848/0.8848

1

lhs=rhs

hence proved
