" (iii) "(4)^(x+1)+(4)^(1-x)=10

Find x , if (1/4)^(-4)x\ (1/4)^(-8)=(1/4)^(-4x)

Solve each of the following quadratic equations: 4^((x+1))+4^((1-x))=10

find the value of x if 4^(x+1) + 4^(x-1) - 10 = 0

lim_ (x rarr oo) ((x + 1) ^ (4) - (x-1) ^ (4)) / ((x + 1) ^ (4) + (x-1) ^ (4))

Solve for x in (4x-1)/(4x+1)+(4x+1)/(4x-1)=(10)/(3)

If 4^(1+x)+4^(1-x)=10 , find x.

lim_(x rarr oo) ((x+2)^(10)+(x+4)^(10)+...+(x+20)^(10))/(x^(10)+1)= ______.

lim_(x rarr a){[(a^((1)/(2))+x^((1)/(2)))/(a^((1)/(4))-x^((1)/(4))))^(-1)-(2(ax)^((1)/(4)))/(x^((3)/(4))-a^((1)/(4))x^((1)/(2))+a^((1)/(2))x^((1)/(4))-a^((3)/(4)))]^(-1)-sqrt(2)^(log_(4)a)}^(8)

If y=log((1-x^(2))/(1+x^(2))), then (dy)/(dx)=(4x^(3))/(1-x^(4))( b) -(4x)/(1-x^(4))( c) (1)/(4-x^(4))(d)-(4x^(3))/(1-x^(4))

If y=log((1-x^2)/(1+x^2)) , then (dy)/(dx)= (a) (4x^3)/(1-x^4) (b) -(4x)/(1-x^4) (c) 1/(4-x^4) (d) -(4x^3)/(1-x^4)
