Question

Arrange the following numbers which are represented using exponents in the ascending order:

• A. $4\times {10}^4$
• B. $4.5\times {10}^5$
• C. $5\times {10}^5$
• D. $4.5\times {10}^6$
• E. $1\times {10}^7$

Answer 1

$4\times {10}^4=40000$

$4.5\times {10}^5=450000$

$5\times {10}^5=500000$

$4.5\times {10}^6=4500000$

$1\times {10}^7=10000000$

40000 < 450000 < 500000 < 4500000 < 10000000

Hence, the ascending order of the given numbers is
$4\times {10}^4<4.5\times {10}^5<5\times {10}^5<4.5\times {10}^6<1\times {10}^7$
