Answer:
50 times greater
Step-by-step explanation:
If there are two numbers A and B, where A is greater than B,
If we want to find how many times greater A is to B, we simply divide, so that would be
A/B
Now, we have
[tex]5*10^{22}[/tex]
and
[tex]1*10^{21}[/tex]
We simply need to divide to find how much greater is the first number than the second number. Remember dividing numbers in scientific notation:
[tex]\frac{a*10^b}{c*10^d}\\=(\frac{a}{c})*10^{b-d}[/tex]
Thus, we have:
[tex]\frac{5*10^{22}}{1*10^{21}}\\=(\frac{5}{1})*10^{22-21}\\=5*10^{1}\\=5*10\\=50[/tex]
So the first number is 50 times greater than the second
