Question:

The value of $\frac{(0.72)^3 - (0.28)^3}{(0.72)^2 + 0.72 \times 0.28 + (0.28)^2}$ is: / $\frac{(0.72)^3 - (0.28)^3}{(0.72)^2 + 0.72 \times 0.28 + (0.28)^2}$ का मान है:

1.
1 / 1
2.
1.44 / 1.44
3.
0.044 / 0.044
4.
0.44 / 0.44

Correct Answer: 0.44 / 0.44

Using the identity $\frac{a^3 - b^3}{a^2 + ab + b^2} = a - b$ with a = 0.72 and b = 0.28, the value equals 0.72 - 0.28 = 0.44. / सर्वसमिका $\frac{a^3 - b^3}{a^2 + ab + b^2} = a - b$ में a = 0.72 और b = 0.28 रखने पर मान = 0.72 - 0.28 = 0.44 प्राप्त होता है।
