The 1906 San Francisco earthquake registered 8.2 on the Richter scale. Using the above equation, the released energy was

# Solve for x: lg(8x+9) + lgx = 1 + lg(x^2 - 1) Given the logarithm equation:
lg (8x+9) + lg (x) = 1+ lg (x^2-1)
We need to find x value.
We will use logarithm properties to solve.
First, we know that lg a + lg b = lg (ab)
==> lg (x(8x+9) = 1 + lg (x^2 -1)
Also, we know that lg 10 = 1
==> lg (8x^2 + 9x) = lg 10... | HuggingFaceTB/finemath | |
