Answer:
1.99750312 * 10 ^(-12)
Step-by-step explanation:
When we divide numbers in scientific notation
1.6*10^12
----------------
8.01 * 10^23
We divide the numbers out front and subtract the exponents on the powers of 10
(1.6/8.01) * 10^(12-23)
.199750312 * 10^(-11)
But this is not proper scientific notation. We need 1 number in front of the decimal. If we move the decimal 1 place to the left, we subtract 1 from the exponent
1.99750312 * 10 ^(-11-1)
1.99750312 * 10 ^(-12)
