Scientific Notation Question?

Question

I can't figure out how to put -80,640 in scientific notation. Can someone help me please? Thanks, appreciate it.

Answer 1

for scientific notation the number has to be between 0 and 10 (or in this case -10 and 0), so you move the decimal place to the left 4 times, getting -8.0640. since you moved the decimal place 4 times, the 10 (in the notation) has be to raise to the 4th power. your answer is -8.064 x 10^4

Answer 2

Writing negatives in scientific notation is almost the same as writing positives in scientific notation. But if you have a negative, move the decimal so that the number is between 0 and -10.



-80,640.

Move the decimal 4 places to -8.0640

Your answer is -8.0640 x 10^4

Answer 3

-8.064 x 10^4



Remember, your first number must have an absolute value greater than or equal to 1, and less than 10. Make the exponent correspond to the desired answer once this is done.

Answer 4

The answer is -8.064 to the 10,000 power
