Question

Trommers a and mare shown as they appear in scientific notation on a scientific calculator display 1.2.12 Which expression represents the quotient of - written in scientific notation? (5x100 D Sx100

Answer 1

n = 1.2 E 12

m = 2.4 E14

`(n)/(m)=(1.2*10^(12))/(2.4*10^(14))`
`=(1.2)/(2.4)*10^(12-14)`
`=(1.2)/(2.4)*10^(-2)`
`=0.5*10^(-2)`
`=5*10^(-3)`
