Question

Compare: 4.3 x 10^6 O 12 x 10^5A.>B.

Answer 1

To check the bigger or smaller number, we can adjust the numbers such that they both have the same exponential power.

The first number can be written as shown below:

`4.3*10^6=4.3*10*10^5=43*10^5`

Now, both numbers have the same exponent. Therefore, we can compare the numbers 43 and 12.1.

Observation of the numbers on the number line shows that:

`43>12.1`

Therefore, we have that:

`43*10^5>12.1*10^5`

The correct option is OPTION A.
