limit as x approaches 8 of (x^2-64)/(x^2-8x)

x \to 8 lim (\frac{x ^{2} - 64}{x ^{2} - 8 x})

2

Solution steps

x \to 8 lim (\frac{x ^{2} - 64}{x ^{2} - 8 x})

Simplify

\frac{x ^{2} - 64}{x ^{2} - 8 x} : \frac{x + 8}{x}

= x \to 8 lim (\frac{x + 8}{x})

Plug in the value

x = 8

= \frac{8 + 8}{8}

Simplify

= 2

\frac{\partial}{\partial x} (2 x + 1)

\int (\frac{8}{x ^{3}}) d x

f (x) = 2 x^{3} - 3 x^{2} - 16 x + 3, at x = - 4

\frac{d}{d x} ((e^{x})^{s i n (x)})

y = x^{3} - 7 x^{2} + 16 x + 7
