Question

71. (1) माना कि ( 0.2=a ) एवं ( 0.04=b ) ( therefore 0.4=2 a ) एवं ( 0.08=2 mathrm{b} )
( therefore )
व्यंजक
( =sqrt[3]{frac{a times a times a+b times b times b}{2 a times 2 a times 2 a+2 b times 2 b times 2 b}} )
( =sqrt[3]{frac{a^{3}+b^{3}}{8left(a^{3}+b^{3}right)}}=sqrt[3]{frac{1}{8}}=frac{1}{2}=0.5 )

# |0.2x0.2x0.2 + 0.04x0.04x0.04 (0.4x0.4x0.4+ 0.08x0.08x0.08 का मान है। (1) 0.5 (2) 0.25 (3) 0.75 (4) 0.125

Solution
