Can you please help me prove logb 18=1.3

Sagot :

Until you specify a value for 'b', there's nothing to prove.
The equation says "When 'b' is raised to the 1.3 power, the result is 18".
The statement is true if b=9.23835 (rounded).


If you had just written the equation and said that  b = approximately 9.23835,
then in order to prove the statement, I would find  (9.23835 ^ 1.3).

According to my calculator,  (9.23835 ^ 1.3) = 18.00001 (rounded) .

To me, that would be a big QED.
