Answer: 30 is the least common multiple of 6 and 10.
Step-by-step explanation:
30/6= 5
30/10= 3.
Question 1. -3 + v5 = 0
Work : -3 + 5v = 0
5v = 3 ( divide )
answer v = 3/5
Question 2. 1 - 7B = -20
work : -7b = -20 - 1
-7b = -21 ( divide )
answer b = 3
question 3 : -k - 5 = 0
work : -k = 5
answer : k = - 5
Question 4 : -1 + 8a = 129
work : 8a = 129 + 1
8a = 130 (divide )
answer a = 65/4
Using order of operations, we can see we should first solve for the exponents, and then multiply the exponent values by each other.
3²×

9×243
2187
Another way to solve this is to add the exponents together and simply do

. We can only do that in this case, however, because the values are being multiplied by each other.
Either way we solve, we will get
2187 as our final answer.
