Question on: WAEC Mathematics - 2012
Which of these statements about y = 8\(\sqrt{m}\) is correct?
A
log y = log 8 x log \(\sqrt{m}\)
B
log y = 3 log 2 x \(\frac{1}{2}\) log m
C
log y = 3 log 2 - \(\frac{1}{2}\) log m
D
log y = 3 log 2 + \(\frac{1}{2}\) log m

Correct Option: D
y = 8\(\sqrt{m}\); log y = log 8\(\sqrt{m}\)
log y = log 8 + log \(\sqrt{m}\)
log y = log 23 + log m\(\frac{1}{2}\)
log y = 3 log 3 + \(\frac{1}{2}\) log m
log y = log 8 + log \(\sqrt{m}\)
log y = log 23 + log m\(\frac{1}{2}\)
log y = 3 log 3 + \(\frac{1}{2}\) log m
