Question 1005734
Solve the following equations 
a) 3^m=81
3^m = 3^4
m = 4
----------------- 
b) (36p^4)12=24
36p^4 = 2
--
p^4 = 1/18
p = (1/18)*18^(1/4)
-------------------------- 
c) 5^n×5^(n+4)=25
5^(2n+4) = 5^2
2n+4 = 2
2n = -2
n = -1
--------------------

d) 4^7x/256=64^2x+2/16^2x−1 
------
(2^2)^(7x)/2^8 = (2^6)^(2x)/(2^4)^(2x-1)
------
[2^(14x-8) = [2^(12x)/2^(8x-4)]
======
2^(14x-8) = 2^(4x+4)
-------
14x-8 = 4x+4
10x = 12
x = 1.2
