Question

Write your answer in scientific notation and Stanford form.

$(1.2 \times {10}^{7})(4 \times {10}^{ - 2})$
​

Answer 1

1.2 x 10000000 = 12000000
4 x .10 = .4
12000000 x .4 = 4,800,000
= 4.8 x 10^6
The little numbers after the 10 tells you how many times you move the numbers decimal. We do this so we can simplify bigger numbers.
