Question

Solve. Answers should be in Scientific Notation.
(3.2 x 10^4) x (1.4 x 10^3)
(8.4 x 10^8) / (2.2 x 10^2)

Answer 1

2.0

Answer 2

for the first

Answer 3

Do you solve the actual notation before you compute, or is there a way to compute it without having to do all of that?

Answer 4

the actual notation

Answer 5

\[(3.2 \times 10^4) \times (1.4 \times 10^3)\]
\[=(3.2\times 1.4)\times 10^{4+3}=4.48\times 10^7\]

Answer 6

similarly,
\[(8.4 \times 10^8) \div (2.2 \times 10^2)=8.4\div 2.2\times 10^{8-2}=3.82\times 10^6\] but
\[\frac{8.4}{2.2}=\frac{84}{22}=\frac{42}{11}\] and non repeating non terminating decimal
