Question

Evaluate:
$(0.05{)}^3$

Answer 1

The above question can be written as, $\left(0.05\right)\times \left(0.05\right)\times \left(0.05\right)$

First we find the product, $\left(5\right)\times \left(5\right)=25$

$\therefore 5\times 5\times 5=\left(25\right)\times \left(5\right)=125$

Total number of decimal places in the given product $=6$

So, the product must contain $6$ places of decimals

$\therefore (0.05{)}^3=0.000125$
