The question has to do with scientific notation

<h3>What is scientific notation?</h3>

Scientific notation is the expression of a number in the form a ×  10ⁿ where 1 ≤ a ≤ 10 and n is an integer.

<h3>How to simplify the expression?</h3>

Now to simplify the expression (9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) both number have to have the same exponent to the power of 10.

So, re-writing, we have

(9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) = (9 × 10⁻¹³) - (6.3 × 10⁻¹³ × 10⁻²)

= (9 × 10⁻¹³) - (6.3 × 10⁻² × 10⁻¹³ )

= (9 × 10⁻¹³) - (0.063 × 10⁻¹³ )

= (9 - 0.063) × 10⁻¹³ )

= 8.937 × 10⁻¹³

So, simplifying the expression (9 × 10⁻¹³) - (6.3 × 10⁻¹⁵) = 8.937 × 10⁻¹³
