Answer:
70
Step-by-step explanation:
1+9+40-40+40+10*2
----------------------- 20
10+40-40+40+20
50 (-40+40 cancels out to 0) +20
50+20= 70
(Following PEMDAS)
Multiply, add, subtract.
if you were to instead go through it left to right, you would get 120, which is incorrect.
15% ------- 75
100% ---- n
n=(100*75)/15=500
n=500
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
