Let u(x) and v(x) be differentiable functions such that (u(x))/(v(x))= 7. If (u'(x)/(v'(x))= p and ((u'(x))/(v'(x)))' = q, then (p+q)/(p-q) has the value of to (a) 1 (b) 0 (c) 7 (d) -7

If x + (1)/(x) = 1 " and" p = x^(4000) + (1)/(x^(4000)) and q is the digit at unit place in the number 2^(2^(n)) + 1, n in N abd n gt 1 , then p + q is .

If x + (1)/(x) = 1 " and" p = x^(4000) + (1)/(x^(4000)) and q is the digit at unit place in the number 2^(2^(n)) + 1, n in N abd n gt 1 , then p + q is .

Let u(x) and v(x) are differentiable functions such that (u(x))/(v(x))=7 . If (u '(x))/(v '(x))=p and ((u(x))/(v(x)))^'=q , then (p+q)/(p-q) has the value equal to 1 (b) 0 (c) 7 (d) -7

Let u(x) and v(x) be differentiable functions such that (u(x))/(v(x))=7. If (u'(x))/(v'(x))=p and ((u'(x))/(v'(x)))=q, then (p+q)/(p-q) has the value of to (a) 1 (b) 0 (c) 7 (d) -7

Let u(x) and v(x) be differentiable functions such that (u(x))/(v(x))=7. If (u'(x))/(v'(x))=p and ((u'(x))/(v'(x)))=q, then (p+q)/(p-q) has the value of to (a) 1 (b) 0 (c) 7 (d) -7

Let u(x) and v(x) be differentiable functions such that (u(x))/(v(x))=7 . If (u'(x))/(v'(x))=p and ((u(x))/(v(x)))^'=q , then (p+q)/(p-q) has the value of (a) 1 (b) 0 (c) 7 (d) -7

If P = (x^(2) -36)/(x^(2) -49) and Q= (x+6)/(x+7) find the value of (P)/(Q)
