Multiplying in Scientific Notation

Multiplying… n The general format for multiplying is as follows… n (N x 10 x)(M x 10 y) = (N)(M) x 10 x+y n First multiply the N and M numbers together and express an answer. n Secondly multiply the exponential parts together by adding the exponents together.

Multiplying… n Finally multiply the two results for the final answer. n (2. 41 x 104)(3. 09 x 102) – 2. 41 x 3. 09 = 7. 45 – 4+2=6 – 7. 45 x 106

Dividing in Scientific Notation

Dividing… n The general format for dividing is as follows… n (N x 10 x)/(M x 10 y) = (N/M) x 10 x-y n First divide the N number by the M number and express as an answer. n Secondly divide the exponential parts by subtracting the exponent from the exponent in the upper number.

Dividing… n Finally multiply the two results together to get the final answer. n (4. 89 x 107)/(2. 74 x 104) n 4. 89 / 2. 74 = 1. 78 n 7– 4=3 n 1. 78 x 103
