Step-by-step explanation:
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
[tex]1.3 \times 10 ^3[/tex]
Next, is [tex]987[/tex]
Smaller than this, next is :-
[tex]1.3 \times 10^1[/tex]
A number with negative power is smaller.
So, last is
[tex]1.57 \times 10^{-4}[/tex]
Hope it helps :)
