The 2 to the power of 2 add the 4 will be in the parenthesis. This is just a tip for you, just try the parenthesis where you think is right and do the math. If it is not right then move the parenthesis.
Answer:
A
Step-by-step explanation:
logb √(41/97)
Square root can be written in exponent form:
logb (41/97)^½
Using log exponent rule:
½ logb (41/97)
Using log quotient rule:
½ (logb 41 - logb 97)
