Answer:
107
Step-by-step explanation:
Plug in 11 for a, and 8 for b.
a + ab + b
(11) + (11 * 8) + (8)
Remember to follow PEMDAS. First multiply, then combine terms:
11 + (11 * 8) + 8
11 + (88) + 8
99 + 8
107

Step-by-step explanation:
Answer:
The first earthquake is 1.9 times greater than the second
Step-by-step explanation:
We need to substract
M1 and M2
M1 - M2 = ㏒(x1/c) - ㏒(x2/c)
by properties of the logarithm
= log(x1) - log(c) - (log(x2) - log(c))
= log(x1) - log(x2)
But, we know that x1 = 80*x2
So,
= log(80) + log(x2) - log(x2)
= 1.903
