Whole numbers are 0, 1, 2, 3, ...... and so on.You can also say that whole numbers include positive integers along with zero.Also decimal number or a fraction are not whole numbers.

Given,\( a+2 b=5 ; \)We have to show that  \( a^{3}+8 b^{3}+30 a b=125 \) \( a+2 b=5 \)Cubing both sides:\( (a+2 b)^{3}=(5)^{3} \)\( \Rightarrow a^{3}+(2 b)^{3}+\{3 a \times 2 b(a+2 b)\}=(5)^{3} \)\( \Rightarrow a^{3}+8 b^{3}+6 a b(a+2 b)=125 \)\( \Rightarrow a^{3}+8 b^{3}+6 a b(5)=125 \)\( ( \) as, \( \quad a+2 b=5) \)\( \Rightarrow a^{3}+8 b^{3}+30 a b=125 \)
