Question

5 × 10 to the power of 22 is how many times greater than 1 × 10 to the power of 21

Answer 1

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

$5*10^{22}$

and

$1*10^{21}$

We simply need to divide to find how much greater is the first number than the second number. Remember dividing numbers in scientific notation:

$\frac{a*10^b}{c*10^d}\\=(\frac{a}{c})*10^{b-d}$

Thus, we have:

$\frac{5*10^{22}}{1*10^{21}}\\=(\frac{5}{1})*10^{22-21}\\=5*10^{1}\\=5*10\\=50$

So the first number is 50 times greater than the second
