Question

An earthquake measured 8.4 on the Richter Scale. Use the formula R = log I to find the intensity, I, of the earthquake.​ NO LINKS!!

Answer 1

I ≈ 251188643

Explanation:

Given

R = logI [ note log I =
`log_(10)` I ]

Using the rule of logarithms

`log_(10)` x = n ⇒ x =
`10^(n)`

Substitute R = 8.4 into the equation, then

logI = 8.4

I =
`10^(8.4)` ≈ 251188643
