Question on: JAMB Mathematics - 2008
Make Q the subject of the formula when L = (\frac{4}{3}) m(\sqrt{PQ})
A
\(\frac{9L^2}{16m^2P}\)
B
\(\frac{3L}{4m \sqrt{P}}\)
C
\(\frac {\sqrt{3L}}{4mP}\)
D
\(\frac{3L^2}{16m^2P}\)
Ask EduPadi AI for a detailed answer
Correct Option: A
L = (\frac {4}{3}) m (\sqrt{PQ})
make Q the subject
(\frac {L}{1}) = (\frac {4}{3}) m (\sqrt{PQ})
3L = 4m (\sqrt{PQ})
Taking the square of both sides
(3L)2 = (4m (\sqrt{PQ}))
(\frac {9L^2}{16m^2P}) = (\frac {16m^2PQ}{16m^2P})
Q = (\frac {9L^2}{16m^2P})
