limit as x approaches 0 of ((484+x)^{0.5}-22)/x

x \to 0 lim (\frac{( 484 + x ) ^{0.5} - 22}{x})

\frac{1}{44}

Decimal Notation

0.02272 \dots

Solution steps

x \to 0 lim (\frac{( 484 + x ) ^{0.5} - 22}{x})

Multiply by the conjugate of

(484 + x)^{0.5} - 22 : \frac{x}{( 484 + x ) ^{0.5} + 22}

= x \to 0 lim (\frac{\frac{x}{( 484 + x ) ^{0.5} + 22}}{x})

Simplify

\frac{\frac{x}{( 484 + x ) ^{0.5} + 22}}{x} : \frac{1}{( x + 484 ) ^{\frac{1}{2}} + 22}

= x \to 0 lim (\frac{1}{( x + 484 ) ^{\frac{1}{2}} + 22})

Plug in the value

x = 0

= \frac{1}{( 0 + 484 ) ^{\frac{1}{2}} + 22}

Simplify

\frac{1}{( 0 + 484 ) ^{\frac{1}{2}} + 22} : \frac{1}{44}

= \frac{1}{44}

f (x) = x^{4} - 10 x^{2} + 9, at x = 2

x \to 2 lim (\frac{3}{( x - 2 ) ^{2}})

\int 2 x + 1 d x

\frac{d}{d x} (arctan (7 x^{2} - 1))

\frac{d}{d x} (\frac{8 x ^{2} + 2 x + 4}{x})
