2  2 X =16  2 X = 2 4  X=4

3  =343  = 7 3  = 3 /.2  x = 6

5  5 x+1 +5 x+2 = 30   3 x+1 - 3 x - 162 = 0   3 x+4 – 3 x+3 + 3 x+2 -3 x+1 + 3 x = 4 941

6  5 x+1 +5 x+2 = 30

7  5 x. 5 1 + 5 x. 5 2 = 30

8  5 x+1 +5 x+2 = 30  5 x. 5 1 + 5 x. 5 2 = 30  5 x. (5+5 2 ) =30

9  5 x+1 +5 x+2 = 30  5 x. 5 1 + 5 x. 5 2 = 30  5 x. (5+5 2 ) =30  5 x. (30) =30 / :30

10  5 x+1 +5 x+2 = 30  5 x. 5 1 + 5 x. 5 2 = 30  5 x. (5+5 2 ) =30  5 x. (30) =30 / :30  5 x = 1

11  5 x+1 +5 x+2 = 30  5 x. 5 1 + 5 x. 5 2 = 30  5 x. (5+5 2 ) =30  5 x. (30) =30 / :30  5 x = 1  5 x = 5 0  x = 0
