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

Answer:
Mom would required 1 lbs of Sugar and 4 lbs of water.
Step-by-step explanation:
Given:
Amount of Sugar syrup Mom wants to make = 5 lbs
Percentile amount of syrup she needs to make = 20%
Solution:
Let amount of sugar to make 20% syrup be 'x'.
So by definition of proportion we get;

Now Multiplying both side by 5 we get;

So we can say that;
Amount of water = 
Hence Mom would required 1 lbs of Sugar and 4 lbs of water.
