Problems - Fixed-Point, Floating-Point, Scientific, and Engineering Notation

Question 1:
Write the following numbers in scientific, and engineering notation to hundredths place:
a. 20.46
b. 50,420
c. 0.000674
d. 000.0460

Solution 1:
In scientific notation:
a. 20.46 = 2.05 x 10^1

b. 50,420 = 5.04 x 10^4
c. 0.000674 = 6.74 x 10^-4
d. 000.0460 = 4.60 x 10^-2

In engineering notation:
a. 20.46 = 20.46 x 10^0

b. 50,420 = 50.42 x 10^3
c. 0.000674 = 674.00 x 10^-6
d. 000.0460 = 46.00 x 10^-3
