Multiply 0.75 by 2.8 * 10 ^ - 5 (1 point)

Question

Generate an image that illustrates the concept of multiplying decimal numbers by each other, specifically involving small multiples of ten, such as 2.8 times 10 to the power of negative 5, and also the number 0.75. The image should contain no text, but could perhaps show graphic representations of the numbers, some sort of scale representing the powers of ten, and a visible act of multiplication.

Multiply 0.75 by 2.8 * 10 ^ - 5 (1 point)

2.1 * 10 ^ - 7

O 2.1 * 10 ^ - 5

O 2.1 * 10 ^ - 4

O 2.1 * 10 ^ - 6

Answer 1

The correct answer is 2.1 * 10 ^ - 6 (Option O).

Answer 2

To multiply 0.75 by 2.8 * 10 ^ -5, follow these steps:

Step 1: Multiply the numeric values: 0.75 * 2.8 = 2.1

Step 2: Add the exponents: -5

Step 3: Write the answer in scientific notation: 2.1 * 10 ^ -5

Therefore, the correct answer is 2.1 * 10 ^ -5.

Answer 3

To multiply 0.75 by 2.8 * 10 ^ - 5, you need to follow these steps:

Step 1: Multiply the decimal numbers: 0.75 x 2.8 = 2.1

Step 2: Multiply the powers of 10: 10 ^ -5 x 10 ^ 0 = 10 ^ (-5 + 0) = 10 ^ -5

Step 3: Combine the results: 2.1 x 10 ^ -5

Therefore, the correct option is "2.1 * 10 ^ - 5".
