Ah, then I have clue how to identify the scientific notation in this problem.
a. 7.8 x 10^-5
b. 3.4 x 100^2
c. 0.84 x 10^6
d. 50 x 50^-12

Could it be.... a? But I'm not sure....

Answer 7

it is!

Answer 8

Thank you! I only said that because I feel that the second number has to have 10. :P

Answer 9

Oh, and I made a mistake. d is 50 x 10^-12

it still can't be d...since 50 is not between 1 and 10! remember...the sign can be negative but the digit must be between 1 and 10!
