Hi, last question in the excercise cant do. Will rep anyone who can clearly explain each step they did and why because i have the answers at the back:
a) Given that 3 + 2log2x = log2y, show that y=8x^2 (The 2 is a small 2 representing the base in each case.
b) Hence or otherwise, find the roots (alpha) and (beta) where alpha<beta, of the equation 3 + 2log2x = log2(14x-3) Again the 2 is small on both.
c) Show that log2alpha = -2
d) Calculate log2beta, giving your answer to 3 sig figs.
Thanks in advance,
Regards, Asad
