7^3
An exponent tells how many times the base is used as a factor. 10^3 = 10 x 10 x 10
0.007030536883856
An exponent is written a half space above the line, so for example, in the number 103, the 3 is an exponent, which instructs us to multiply 10 by itself 3 times, so that the result is a thousand.
you get an exponent when you multiply EXAMPLE 10x10x10=1000 that is an exponent NO DONT THINK THAT IF THE EXPONENT IS 3 YOU MULTIPLY IT BY 3 NO WAY JOSE
Assuming the bases are the same, you add the exponents. 10^3 x 10^3 = 10^6
7^3
An exponent tells how many times the base is used as a factor. 10^3 = 10 x 10 x 10
4.816 x 10-3 = 0.004816
1*10-3
3
One-thousandth, 1 x 10-3
The exponent in this case is the small number written in superscript (raised) to the right of the 10.

.755 x 10-3 (-3 is an exponent)
3.43*10-3 = 3.43/1000 = 0.00343
