Question

Evaluate:
$(1.5{)}^3$

Answer 1

The above question can be written as, $\left(1.5\right)\times \left(1.5\right)\times \left(1.5\right)$

First we find the product, $\left(15\right)\times \left(15\right)=225$

$\therefore 15\times 15\times 15=\left(225\right)\times \left(15\right)=3375$

Total number of decimal places in the given product $=3$

So, the product must contain $3$ places of decimals

$\therefore (1.5{)}^3=3.375$
