Answer:
2 - 
Step-by-step explanation:
Using the addition formula for tangent
tan(A - B) =  and the exact values
 and the exact values
tan45° = 1 , tan60° =  , then
 , then
tan15° = tan(60 - 45)°
tan(60 - 45)°
= 
=  
 
Rationalise the denominator by multiplying numerator/ denominator by the conjugate of the denominator.
The conjugate of 1 +  is 1 -
 is 1 -  
 
=  ← expand numerator/denominator using FOIL
 ← expand numerator/denominator using FOIL
= 
= 
=  +
 + 
= 2 - 
 
        
             
        
        
        
98^2 = (100-2)^2
Using (a-b)^2, we have
= (100)^2-2(100)(2)+(2)^2
= 10000-400+4
= 10004-400
= 9604
The answer is 9604.

Answer and Step-by-step explanation:

The domain is all real numbers <u>except</u> 9 (positive)
This is because we can't have 0 in the denominator, and when x equals 9, then the denominator is 0. Anything divided by 0 is undefined, which is why 9 (in this equation) is <u>not</u> included.
