$\lim_{x\to0}\left(\frac{\sqrt{1-x}-\sqrt{1+3x}}{x}\frac{\sqrt{1-x}+\sqrt{1+3x}}{\sqrt{1-x}+\sqrt{1+3x}}\right)$
Learn how to solve limits by direct substitution problems step by step online. Find the limit of ((1-x)^(1/2)-(1+3x)^(1/2))/x as x approaches 0. Applying rationalisation. Multiply and simplify the expression within the limit. x+0=x, where x is any expression. Combining like terms -x and -3x.
