Answer 1

Explanation:

Question:-

Order these numbers from largest at the top, to smallest at the bottom.

1.57x10^-4

4.5x10^3

1.3x10^1

987

We can see that:-

The exponent with highest power is the largest number.

Here, the largest number is

`1.3 * 10 ^3`

Next, is
`987`

Smaller than this, next is :-

`1.3 * 10^1`

A number with negative power is smaller.

So, last is

`1.57 * 10^(-4)`

Hope it helps :)
