The value of the addition operation is 2.38157 x 10^19
<h3>How to add the numbers/expressions?</h3>
The numbers are given as:
2.35 x 10^19 and 3.157 x 10^17.
Express as sum
2.35 x 10^19 + 3.157 x 10^17.
Express 10^17 as 10^19 * 10^-2
So, we have:
2.35 x 10^19 + 3.157 x 10^19 * 10^-2
Factor out 10^19
(2.35 + 3.157 * 10^-2) x 10^19
Express 10^-2 as 0.01
(2.35 + 3.157 * 0.01) x 10^19
This gives
(2.35 + 0.03157) x 10^19
Evaluate the sum
2.38157 x 10^19
Hence, the value of the addition operation is 2.38157 x 10^19

Answer:
198
Step-by-step explanation:
In order for them to be a proportion, they must be equal. 9 as a fraction is 9/1, so you need to figure out what over 22 = 9/1. so you need to multiply 1 by 22 to get 22 in the denominator, so for the numerator, you multiply 9x22, which is 198.
198/22 : 9
Answer:
dunno
Step-by-step explanation:
Answer:
Length = 72 mm
Width = 46 mm
Ratio = 72:46 = 36:23
Step-by-step explanation:
72 and 36 both are divisible by 2. so when we divide them by two we get 36 and 23. we can divide both the sides only with the same number, but 36 and 23 have no common factors. so we leave it here and this is the answer.
