F4 MATH log
The energy released as seismic waves in an earthquake is 1/8 times that in
another earthquake with a magnitude of 7.2 on the Richter scale.
Find the magnitude of the first earthquake on the Richter scale.
(Give your answer correct to 1 d.p)
(log E = 1.5M + K ,where K is a constant)

sub magnitude of 7.2 in to equation log E = 1.5M + K.
log E = 1.5(7.2) + K ______(1)
The energy released as seismic waves in an earthquake is 1/8 times
sub (1) into (2)
1.5(7.2) + K-log8=1.5M+K
