Express each answer to the proper number of significant digits.
a. (149 x 10^6) x (0.21 x 10^3)
My answer: 3.1 x 10^10
b. (0.371 x 10^14) / (2 x 10^4)
My answer: 2 x 10^11
c. (6 x 10^6) x (6 x 10^6)
My answer: 4.0 x 10^13 (I'm thinking it's 4 x 10^13 because there is only one significant digit.)
d. (0.1186 x 10^6) x (12 x 10^-5)
My answer: 1.4 x 10^1
Are my answers correct?
