Question

Which of these numbers has the least value?A.3,213,213B.7.8 x 10*5C.6.3 x 10*6D.11,014,114

Answer 1

To figure out which number has the least value, we can convert all the numbers into the standard form with identical powers, say 6.

Doing that, we have the numbers to be:

Option A:

`3.2*10^6`

Option B:

`0.78*10^6`

Option C:

`6.3*10^6`

Option D:

`11.01*10^6`

Given that all the numbers have identical bases, we can arrange the numbers in descending order as shown below:

`11.01>6.3>3.2>0.78`

Therefore, the number with the least value is:

`7.8*10^5`

OPTION B is the correct option.
