How to calculate X^n using normal calculator ?

Let me explain it to you with an example.

Suppose we want to calculate (1.089)^1.2

Step-1 : Put down the base (1.089) in your calculator and now press the √ (Square root) key 12 times.

(In our example we will get 1.0000208156)

Step-2 : Now subtract 1 from the number we get in step 1.

(In our example we will get 1.0000208156 -1=0000208156)

Step-3 : Now multiply the number in step 2 with the power 'n'

(In our example 1.2, 0000208156 X 1.2 = 0.00002497872)

Step-4 : Add back one to the number we get in step 3

(In continuation of our example, the no we get is 1.00002497872)

Step-5 : In the final step press "X =" keys ('Multiplication' and 'Equal To' keys one after the other) 12 times

(Our answer is 1.00002497872 X=, X=, X=......... 12 times, we will get 1.10772851898 says 1.1077)
