Question

Calculate (4.014 x 10 ^−8) + (3 x 10 ^−8).

4.017 x 10 ^−16
7.014 x 10 ^−16
7.014 x 20 ^−8
7.014 x 10 ^−8

Answer 1

The answer is 7.014 x 10 ^-8

STEPS TO SOLVING
1. remove unnecessary parenthesis. since there’s a addition symbol between the parenthesis the equation doesn’t change

2. Then you collect like terms by adding 4.014 and 3 together making 7.014 meanwhile the second 10^-8 rules out keeping only one

Sorry if this didn’t make sense I was trying to explain it as simple as I could :)

Answer 2

The value of the expression (4.014 x 10⁻⁸) + (3 x 10⁻⁸) will be 7.014  x 10⁻⁸. Then the correct option is D.

What is a PEMDAS rule?

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The expression is given below.

⇒ (4.014 x 10⁻⁸) + (3 x 10⁻⁸)

Simplify the expression, then the value of the expression will be

⇒ (4.014 x 10⁻⁸) + (3 x 10⁻⁸)

⇒ (4.014 + 3) x 10⁻⁸

⇒ 7.014  x 10⁻⁸

The value of the expression (4.014 x 10⁻⁸) + (3 x 10⁻⁸) will be 7.014  x 10⁻⁸. Then the correct option is D.
