Question 121006
when you multiply in scientific notation, you multiply the coefficients (regular numbers) and add the powers of 10


(8.3*10^-5)(2*10^12)=(8.3*2)*10^(-5+12)=16.6*10^7
__ remember, only one number to the left of the decimal, so 1.66*10^8
__ the coefficient got smaller so the exponent had to get larger to keep the value the same


the other two problems work the same way
