What is 8.751 × 101^1 in standard notation?
a. 875,100,000
b.8,751,000,000
c.8,751,000,000,000
d.875,100,000,000

I guess the scientific notation that is in is question is written with a typo. It would b 8.571 x 10^{11}. This would mean that you need to move the decimal eleven spaces to the left. If you had a negative exponent then the decimal would move eleven spaces to the left.

But if you move the decimal eleven spaces to the right then you would get:
857,100,000,000
