Answer:

6.958 x 10^-13

Step-by-step explanation:

(7x10^-13) - (4.2x10^-15) = 6.958E-13

I took away the E and saw back on the first parentheses. There was a 10^-13 so i got the idea to take that piece into the answer.

side note - I was actually haven't been taught this yet, this is a complete guess. Notify me if I'm wrong (I probably am)

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.

What is subtraction?

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.
