Given: $(i)$. $5,00,00,000$ $(ii)$. $70,00,000$ $(iii)$. $3,18,65,00,000$

$(iv)$. $3,90,878$ $(v)$. $39087.8$ $(vi)$ $3908.78$


To do: To express the above numbers in standard form.

Solution:
$(i)$. $5,00,00,000$

$=5\times10000000$


$=5\times10^7$

$(ii)$. $70,00,000$

$=7\times1000000$

$=7\times10^6$

$(iii)$. $3,18,65,00,000$

$=3.1865\times 10^9$

$(iv)$. $3,90,878$

$=3.90878\times10^5$

$(v)$. $39087.8$

$=390878\times 10^4$

$(vi)$ $3908.78$

$=3.90878\times 1000$

$=3.90878\times 10^3$
