Indices & Logarithm

Let's make it easy to solve 'Indices Equation'...u just remember 3 types of indices equation...

First : By equating the base

a^x = a

Example:
Solve the equation of 2^(x+1) = 4^x

Solution2^(x+1) = 4^x
2^(x+1) = 2^(2x)
x+1 = 2x
Therefore, x = 1

Second : Using Logarithm
a^x = b

Example:

Solve the equation 5^x = 8

Solution:

5^x = 8
log 5^x = log 8
x log 5 = log 8
x = log8/log5

Therefore, x = 1.292


Third : Factorise

a^x +ba^x + c
Example :

Given 2^(2x) - 5(2^x) + 4 = 0. Find the value of x

Solution:

2^(2x) - 5(2^x) + 4 = 0
(2^x)^2 - 5(2^x) + 4 = 0

Replace y = 2^x

y^2 - 5y + 4 = 0
(y - 1)(y - 4) = 0
y = 1 or y = 4
2^x = 1 2^x = 4
2^x = 2^0 2^x = 2^2
x = 0 x = 2
