simplify s^2(2+2/s)

Solution

simplify

s^{2} (2 + \frac{2}{s})

s (2 s + 2)

Solution steps

s^{2} (2 + \frac{2}{s})

Join

2 + \frac{2}{s} : \frac{2 s + 2}{s}

= s^{2} \frac{2 s + 2}{s}

Apply the fraction rule:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{s ^{2} ( 2 s + 2 )}{s}

Apply exponent rule:

a^{b + c} = a^{b} \cdot a^{c}

s^{2} = ss

= \frac{ss ( 2 s + 2 )}{s}

Cancel the common factor:

s

= s (2 s + 2)

1 + \frac{K ( s + 1 ) ( s + 2.69 )}{s ^{3}}

\frac{1260}{( 2 x + 3 ) ^{3}}

\frac{5 n ( n + 1 )}{2}

(16 - r^{2}) r^{2} cos (x)

(x - x) (x + x)
