Question
How are numbers expressed in scientific notations (exponential notations)?
✓
Answer
In scientific notations, numbers are expressed in the form of $N \times 10^n,$ where $‘n \ ’$ is an exponent with positive or negative values and $N$ can have a value between $1$ to $10.$
e.g. $i.$ The number, $602,200,000,000,000,000,000,000$ is expressed as $6.022 \times 10^{23.}$
$ii.$ The mass of a $H$ atom, $0.00000000000000000000000166 g$ is expressed as $1.66 \times 10^{-24} g.$
$iii.$ The number $123.546$ is written as $1.23546 \times 10^2.$
$iv.$ The number $0.00015$ is written as $1.5 \times 10^{-4}.$
