  • 10^-4= 1/10^4 = 0.0001

    5×0.0001=0.0005

  • Your number is in scientific notation. The power of ten tells you how far and in what direction to move the decimal point on the 5.

    So when you move the decimal point 4 spaces to the left (left for a negative power, right for a positive power) you’ll get .0005

  • .0005 = 5 ten thousandths

    Here are some powers of 10 that should help you understand:

    (the ^ symbol is “Raised to the power of”)

    10^4 = 10000 = ten thousand

    10^1 = 10

    10^0 = 1

    10^-1 = .1

    10^-4 = .0001 = 1 ten thousandth

  • the number is expressed in scientific notation

    which is also equal to 0.0005

    it like saying divide 5 by ten 4 times. ( because exponent is negative multiply if positive)
