Question

A lake in California contains about 8,500,000,000,000 gallons of water. How can this number be written in scientific notation?
85.0x1011
8x1012
8.5x1011
8.5x1012​

Answer 1

Your answer is D. 8.5 x 10^12. Reason is because if you use a calculator (ex. TI-84 Plus C Silver Edition Calculator), it will say 8.5E12, which is represented 8.5 x 10^12.

Hope this helped!
