Question

$\text{23000 liters}=2.3\times {10}^a\text{milliliters.}$
Find the value of 'a'.

• A. 7

Answer 1

The correct option is A 7
$\text{1 liter}={10}^3\text{milliliters}$

$So,23000\text{liters}=23000\times {10}^3\text{milliliters}$

$\Rightarrow 23000\text{liters}=2.3\times {10}^4\times {10}^3\text{milliliters}$

$\Rightarrow 23000\text{liters}=2.3\times {10}^{4+3}\text{milliliters}$

$\Rightarrow 23000\text{liters}=2.3\times {10}^7\text{milliliters}$

$\therefore \text{Value of a}=7$
