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:
7.
Step-by-step explanation:
21 = 3 * 7
28 = 2 * 2 * 7
42 = 2 * 3 * 7
Collecting common factors:
t is common to all 3 sets of factors so
HCF = 7.
Answer:
2:4 like in a basketball game 2/4 like a fraction 2:4 like a competitive thing
Step-by-step explanation:
6 times 50 is 300, there’s your answer. He was 300 dimes altogether.
My way is 14.50/100 to give you one percent. So one percent is .145 mutiply that by 7 to give you 1.02 so 14.50+1.02=15.52. So 15.52 is the answer.
