Answer 2

Basics:-

To write in scientific notation, we have to use exponents. We have to follow the very basic rule. The number should be in form of :-

$k × 10^n$

where,

$1 < k < 10$

Since it is a very small number, the exponent of 10 should be negative. It is very important to know the rule of exponents.

Answer:-

$0.000000726$

$= \frac{726}{1000000000}$

$= \frac{726}{{(10)}^{9}}$

$= 726 × {10}^{-9}$

$= 7.26 × 10^2 × {10}^{-9}$

$= 7.26 × {10}^{-9+2}$

$= 7.26 × {10}^{-7}$
