Question

Order 34 x 10^2,1.2x10^7,8.11×10-^3 and 435 from least to greatest

Answer 1

The ascending order is
`8.11* 10^(-3),435, 34* 10^2, 1.2* 10^7`

Explanation:

First of all find the exact value of each number.

`34* 10^2=34* 100=3400`

`1.2* 10^7=1.2* 10000000=12000000`

`8.11* 10^(-3)=(8.11)/(1000)=0.00811`

The fourth number is 435.

Using the above calculation we can easily arrange these numbers form least to greatest.

The ascending order is

`0.00811, 435, 3400, 12000000`

It can be written as

`8.11* 10^(-3),435, 34* 10^2, 1.2* 10^7`.
