Question 941456
5x+2  = 101	
a)log5^(x+2)  = log101
log(5^(x+2))  = log(101)
(x+2)*log(5) = log(101)
x+2 = log(101)/log(5)
x = log(101)/log(5) - 2
=======================
b)Log4 (x + 3) - Log4 x = 3
{{{log(4,(x+3)/x) = log(4,4^3)}}}
(x+3)/x = 64
etc.
===================					
c)If log2 y = 15, find the value of log2 8y
= {{{log(2,y) + log(2,8)}}}
= 18
===================				
d)Solve the equation: 52x – 6(5x) = 0
x = 0
