expand 1/(sqrt(x+4))

expand

\frac{1}{x + 4}

\frac{x + 4}{x + 4}

Solution steps

\frac{1}{x + 4}

Multiply by the conjugate

\frac{x + 4}{x + 4}

= \frac{1 \cdot x + 4}{x + 4 x + 4}

1 \cdot x + 4 = x + 4

x + 4 x + 4 = x + 4

= \frac{x + 4}{x + 4}

t \cdot (1 - H (t - 8))

2^{x} - 2^{(2 x + 1)}

- \frac{17 ( 1 + 5 )}{2} + 37

\frac{8 x ^{2} - 22 x + 6}{( 4 x ^{2} + 3 ) ^{2}}

\frac{( 1 + e ^{x} ) \frac{d y}{d x}}{x}
