The value of the expression (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵) will be 6.958 x 10⁻¹³. Then the correct option is C.
<h3>What is subtraction?</h3>
It simply implies subtracting something from an entity, group, location, etc. Subtracting from a collection or a list of ways is known as subtraction.
The expression is given below.
⇒ (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵)
Simplify the equation, then the value of the expression will be
⇒ (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵)
⇒ (7 x 10⁻¹³) − (0.042 x 10⁻¹³)
⇒ 6.958 x 10⁻¹³
The value of the expression (7 x 10⁻¹³) − (4.2 x 10⁻¹⁵) will be 6.958 x 10⁻¹³. Then the correct option is C.

Answer:
Connor gets 400000
Olivia gets 300000
Avery gets 100000
Step-by-step explanation:
You can create the following equation from this:
let c is the amount connor gets:
c + 3/4 c + 1/4 c = 800000
so 2c = 800000
c = 400000
Connor gets 400000
Olivia gets 400000 * 3/4 = 300000
Avery gets 400000 * 1/4 = 100000
