Question

Approximately how many times greater is 6×10−5 than 5×10−9 ?

Answer 1

First, let's solve the first equation. Multiply 10 with 6 first:
6*10=60

Then subtract 5:
60-5=55

Now let's solve the second one. Multiply 5 with 10:
5*10 = 50

Then subtract the 9:
50-9=41

55 and 41 rounded to the nearest tens place are 60 and 40...but I can approximate how many times bigger one number is from the other because they're both under 100. Unless this was meant to have exponents, in which case, follow these steps:

6^10=1,000,000
1,000,000-5 = 999,995

5^10=100,000
100,000-9=99,991

In the case of exponents, 999,995 is about 10 times greater than 99,991.
I hope this answer helped you. If not, please tell me what you think of the answer. Thank you :)

Answer 2

6*10 is 60-5 is 55 and 5*10 is 50-9 is 41 so 55-41 is 14 so 14 times greater.
