Multiply. Write the result in scientific notation.

(1.4 x 10^1)(8 x 10^4)

11.2 x 10^5 or 1.12 x 10^6

Multiply. Write the result in scientific notation.

(1.7 x 10^-4)(5 x 10^-5)

8.5 x 10^-10

To multiply two numbers written in scientific notation, you need to multiply the coefficients and add the exponents.

Step 1: Multiply the coefficients: 1.4 * 8 = 11.2
Step 2: Add the exponents: 10^1 * 10^4 = 10^(1+4) = 10^5

Therefore, (1.4 x 10^1)(8 x 10^4) = 11.2 x 10^5.

In scientific notation, the result is 1.12 x 10^6.

To multiply numbers in scientific notation, you need to multiply the numerical parts and add the exponents. Let's break it down step-by-step:

1. Multiply the numerical parts: 1.4 * 8 = 11.2.

2. Add the exponents: 10^1 * 10^4 = 10^(1+4) = 10^5.

3. Write the result in scientific notation: 11.2 * 10^5.

Therefore, the result in scientific notation is 1.12 x 10^6.
