# 8.73 x 8.73 x 8.73 + 4.27 x 4.27x4.27 8.73 X4.27 - 8.73 x 4.27 + 4.27x4.27 | का. मान क्या है ?

Solution

$\frac{{\left(8.73\right)}^{3}+{(4.27)}^{3}}{{(8.73)}^{2}-(8.73)(4.27)+{(4.27)}^{2}}\phantom{\rule{0ex}{0ex}}\therefore \frac{{a}^{3}+{b}^{3}}{{a}^{2}-ab+{b}^{2}}=a+b\phantom{\rule{0ex}{0ex}}\mathbf{\Rightarrow}\mathbf{8}\mathbf{.}\mathbf{73}\mathbf{+}\mathbf{4}\mathbf{.}\mathbf{27}\mathbf{=}\mathbf{13}\mathbf{}\mathit{a}\mathit{n}\mathit{s}\mathbf{.}$
