Write down the ORDER OF MAGNITUDE for the numbers given:

a)4.72*10^-7
b)8.65*10^4
C)7.59*10^-5

a: 10^-7

b: 10^5
c. 10^-5

Is 8.65*10^4 has the order of magnitude 10^4 or 10^5?

My answeris 10^4

To determine the order of magnitude of a number, you need to count the number of places the decimal point has been moved to the left or right.

a) For 4.72*10^-7, the decimal point has been moved to the left by 7 places. So, the order of magnitude is 7.

b) For 8.65*10^4, the decimal point has been moved to the right by 4 places. So, the order of magnitude is -4.

c) For 7.59*10^-5, the decimal point has been moved to the left by 5 places. So, the order of magnitude is 5.
