Answer:
(a) 
(b) We use the property of exponent that when there is multiplication of two function then there exponent are added
Step-by-step explanation:
We have given expression

(a) We have to find the value of a
We know the property of exponent that when there is multiplication of two function then there is addition of exponent
So 


(b) We use the property of exponent that when there is multiplication of two function then there exponent are added

Step-by-step explanation:
Answer:
The final answers are n = 0 or n = -1/4.
Step-by-step explanation:
Given the equation is -5n(4n + 1) = 0.
The Zero-Product property says "if x*y=0, then x=0 or n=0 or both."
we have -5n(4n + 1) = 0.
We know -5 is not equal to 0.
It means n = 0 or 4n+1 = 0.
n = 0 or 4n = -1.
n = 0 or n = -1/4
So, final answers are n = 0 or n = -1/4.
