13^5 in standard notation
10^9 in standard notation
please hellp me answer tese questions

Do a little investigation and you'll see the pattern
10^0 = 1
10^1 = 1/10 = 0.1
10^2 = 1/100 = 0.01
...
a billion is a thousand million = 10^3 * 10^6 = 10^9
I think you meant 10^5  that would be a 1 with 5 zeros = 10000
