A rectangular flower bed has a length of .0.005 km and a width of 8 x 10 to the negative third power km. What is the area of the flower bed in square km?
8x10^-3 is in scientific notation. The negative in the exponent (the -3) indicates to move the 8's decimal three places to the left to get .008 km. After that, multiply .005 by .008 to get your answer. You should get .00004 square km.
