`lim_(x->0)(2 7^x-9^x-3^x+1)/(sqrt(2)-sqrt(1+cosx))`

Evaluate : lim_(x to 0) (27^x-9^x-3^x+1)/(sqrt2-sqrt(1+cosx))

Evaluate: lim_(xrarr0) (2^x-9^x-3(x+1))/(sqrt2- sqrt1+cosx)

a=lim_(xrightarrow0)(sqrt(1+sqrt(1+x^4))-sqrt2)/(x^4),b=lim_(xrightarrow0)(sin^2x)/(sqrt2-(sqrt(1+cosx)) find ab^3

lim_(x to 0) (2^(x) - 1)/(sqrt(1 + x) - 1) =

lim_(x to 0) (2^(x) - 1)/(sqrt(1 + x) - 1) =

lim_(xto0) ((1-3^(x)-4^(x)+12^(x)))/(sqrt((2cosx+7))-3)

Evaluate: lim_(xto0) ((1-3^(x)-4^(x)+12^(x)))/(sqrt((2cosx+7))-3)

Evaluate: ("lim")_(xvec0)((1-3^x-4^x+12^x))/(sqrt((2cosx+7))-3)

Evaluate: ("lim")_(xvec0)((1-3^x-4^x+12^x))/(sqrt((2cosx+7)-3))
