It is: 5.08*10^8 in scientific notation and the exponent of 10 is 8

I have no idea i just need help with my homework :/

If the exponent is not negative, then a number written in scientific notation is greater than or equal to 1.

The value is 8 because the exponent written in scientific notation is 2.45x10^8, which means 2.45 times 10 to the eighth power.

0.0045 = 4.5 x 10-3

0.0045 = 4.5 x 10-3

The sign of the exponent for a number written in scientific notation depends on whether it is a whole number or a fraction. 40 is 4 x 101 0.4 is 4 x 10-1

Do you mean how is it written in scientific notation? 1.01 X 10^6.

Te exponent would not change if the number is less than 5.

It means that the decimal point has to move to the left.

To write this number in scientific notation, you place the number of times the decimal is moved to the left as the exponent. 238857 miles, or 238,857 miles is written in scientific notation as 2.38857 X 105 miles.

Move 6 decimal places to the right, so the exponent for base 10 is -6. Then, in scientific notation, the term is: 2.13 x 10-6
