Question

using scientific notation
look back and check

1. perform the following calculations. express your answers in scientific notation.

a. \\((7.6 \times 10^{-4}\text{ m}) \times (1.5 \times 10^7\text{ m})\\)
b. \\(0.00053 \div 29\\)

1. calculate how far light travels in \\(8.64 \times 10^4\text{ seconds}\\). (hint: the speed of light is about \\(3.0 \times 10^8\text{ m/s}\\).)

Explanation:

Calculate the product of the first expression

$$
LATEXBLOCK0
$$

Calculate the sum of the second expression

$$
LATEXBLOCK1
$$

Calculate the distance traveled by light

$$
LATEXBLOCK2
$$

Answer:

Question 1

a. \(1.1 \times 10^{4}\text{ m}^2\) (or \(1.14 \times 10^{4}\text{ m}^2\))
b. \(2.9 \times 10^{1}\) (or \(2.900053 \times 10^{1}\))

Question 2

\(2.6 \times 10^{13}\text{ m}\) (or \(2.592 \times 10^{13}\text{ m}\))
