Question

Identity the following example
$\frac{0.43 \times }{0.43 \times } \frac{0.43 \times }{0.43 - } \frac{0.43 + }{ 0.43 \times } \frac{0.37 \times }{0.37 + } \frac {0.37 \times } {0.37 \times } \frac{0.37}{0.37} = x$
Options:
1}0.6
2}0.43
3}0.8
4}0.37​

Answer 1

Answer:

It can be written as (a^3 +b^3)/(a^2 -ab +b^2)

and as the formula for a^3+b^3 = (a+b)(a^2-ab+b^2)

so it will leave only a+b in numerator as 0.43 + 0.37

which is equal to 0.8

so answer will be 3) 0.8
