Question:
If y = (x√x2 – 16)/(2) – 8 log|x + √x2 – 16|, then what is (dy)/(dx) equal to?
If y = (x√x2 – 16)/(2) – 8 log|x + √x2 – 16|, then what is (dy)/(dx) equal to?
Options:
- x – √(x2 – 16)
- √(x2 – 16)
- x√(x2 – 16)
- 4√(x2 – 16)
- x – √(x2 – 16)
- √(x2 – 16)
- x√(x2 – 16)
- 4√(x2 – 16)
Correct Answer: b)
Explanation:
‘ We ha√e,
! y=” 8Inja + a? — 16
1 dy 1 2 7
= = 2 E X EW + √z 19
— 1 2
1 8x z+/z2 16 i + 24/ 2
i 126 8 o+√z?-16
