Question

0.7(3.6 x 10^-2) any answers please

Answer 1

The answer is 0.0252 .

Answer 2

Hi!

We have to use PEMDAS to solve this.

Parentheses

3.6 x 10^-2

Exponents

3.6 x 0.01

Multiplication

0.036

0.7 x 0.036

0.0252

Now let's put it in scientific notation.

The formula for scientific notation is N × 10^a

N = an integer between 1-10

a = how many times it was moved to the left or right of the decimal

Let's turn 0.0252 into an integer between 1-10 by moving the decimal to the left.

2.52

2.52 × 10^a

We moved the decimal to the right (negative) 2 times.

2.52 × 10^-2

The answer is 2.52 × 10^-2

Hope this helps! :)
