Exponential Equation of Linear Form

Under an exponential equation, if the base numbers of any equation are equal, then the power will be equal & vice versa.

 

Examples

     Solve the following exponential equations

              a)  (1/2) x  =  8   b)  (0.25) x+1  =  16    c)  3x = 1/81         d) 10 x = 1/0.001   e)  4/2x = 64 x

Solution

a)       (1/2) X = 8                                                     b)     (0.25) x+1 = 16

(2 -1) x = 2 3                                                                (25/100) x+1 =  42
