4 + 12 + 36... etc
is a sum that can be rewritten in form
4 ( 1, 3, 9, 27, 81, etc) this can further be written in sigma notation:
4 Sigma [ 3 ^ ( i - 1)]
The sum of the indefinite summation will be the limit as i goes to infinity = infinity
Hey there, first you need to know the integers rules. So, how you can see a negative times a positive is negative. So -5 x 1 = -5. -5 x 11 = -55. -55 x 4 = -220
Answer:4w-20
Step-by-step explanation:distribute
The answer is -6300
Explanation:
6.3 x 10^-3
1) Accoring to PEMDAS, we must do 10^-3 first. 10 x 10 x 10 = 1,000, then we add the negative
6.3 x -1000
2) Now we just move the decimal on 6.3 three times to the right, then add the negative
6.3 x -1000
-6300
