1.1 EXPONENTIAL NUMBERS The speed of light is 186,000 miles per second. This is 1.86 x 105 (in exponential form) The diameter of an E. coli cell is 0. meters = 8.0 x 10-7 (in exponential form) . A number larger than one will have a positive exponent. Move the decimal point nine places to the left to give 4.95 x 109 0. A number smaller than one will have a negative exponent. Move the decimal point 13 places to the right to give 5.6 x 10-13 1.) 0. = smaller than 1 = negative exponent, move ...
