Question
Evaluate the following:
$(598)^3$
$(598)^3$
✓
Answer
We know that $(a-b)^3=a^3-b^3-3 a b(a-b)$
$\Rightarrow(598)^3 \text { can be written as }(600-2)^3$
$\text { Here, } \mathrm{a}=600 \text { and } \mathrm{b}=2$
$(598)^3=(600-2)^3$
$=(600)^3-(2)^3-3(600)(2)(600-2)$
$=216000000-8-(3600 \times 598)$
$=216000000-8-2152800$
$=216000000-2152808$
$=213847192$
The value of $(598)^3=213847192$
