Answer:
10¹⁸ ergs
Step-by-step explanation:
From the question,
Using the expression
M =
log(E/10¹³)................. Equation 1
Where M = Richter magnitude of earth quake, E = Energy released in ergs.
Given: M = 4.0
Substitute into equation 1 amd solve for E
4 =
log(E/10¹³)
Log(E/10¹³) = (4×5)/4
Log(E/10¹³) = 5
E/10¹³ = 10⁵
E = 10⁵×10¹³
E = 10⁵⁺¹³
E = 10¹⁸ ergs
5 goes into 62 12 times with a remainder of 2. So technically 62 divided by 5 is 12.4.
Hope this helps!
The answer would be x= 4,-4
