Question

How do you solve logb9=2 and check the solutions?

Answer 1

if a power n is equals to X Y and X are positive integers and a is not equal to 1 then we define the a x base is equals to N read as law of x to the base a is equal to and fro example to power 4 is equals to 16 for log 16 base 2 who is equals to 4 love log its base is a meaningful when X is greater than zero is greater than zero and a is not equal to zero log base 1 is not defined because every power of one is one is not equal to a
