In multiplication, the number of negative signs determine whether positive or negative. The absolute value is determined by multiplying the absolute values. ( 6)( 1)(1)( 5)(2)    60

  1. Write (^8)  10 ^5 in ordinary notation. To change to ordinary notation, perform the operation. 8  10 ^5 0.
  2. Write 3,820,000 in scientific notation. To change to scientific notation, remember that scientific notation needs a number at least 1 but less than 10 times a power of 10. Find the first nonzero digit, so that you have the factor. Then count the places and the direction from this point to the original decimal point, which will give you the exponent. 6 3,820, 000 3.82  10
  3. Perform the indicated operation and write answer in scientific notation. Do not change numbers to ordinary notation: (3.8 10 )(4.2 4 10 )^5 Remember that if the factor after multiplication or division is not in the range between 1 and 10, it must be adjusted. Change the factor to scientific notation and then adjust the exponent. 4 5 4 5 9 1 9 10
