# Amanda is adding the numbers below.What is the sum written in scientific notation?

Answer: Basically what you do is                             (the ^ arrow meaning exponent)
You take 3.7 + 4.45 x 10^20
Then 8.15 x 10^20, remove the decimal of 8.15 = 815 x 10^-2 x 10^20
815 x 10^18 = 815000000000000000000
