How do you change powers in scientific notation?

Answer 1

Multiply the coefficient by 10, moves decimal to the right, changes the exponent to be 1 less. Divide the coefficient by 10, moves decimal to the left, changes the exponent to be 1 more.

Answer 2

To change a number from standard to scientific notation, move the decimal point to create a number between 1 and 10. Count the number of places you moved the decimal point to get the power of 10. If you moved it to the left, the exponent is positive, and if you moved it to the right, the exponent is negative.
