expand-3(ln(5x)+1)

expand

- 3 (ln (5 x) + 1)

- 3 ln (5 x) - 3

Solution steps

- 3 (ln (5 x) + 1)

Apply the distributive law:

a (b + c) = ab + a c

a = - 3, b = ln (5 x), c = 1

= - 3 ln (5 x) + (- 3) \cdot 1

Apply minus-plus rules

+ (- a) = - a

= - 3 ln (5 x) - 3 \cdot 1

Multiply the numbers:

3 \cdot 1 = 3

= - 3 ln (5 x) - 3

\frac{4000 ( s ^{2} + 4 s + 4 )}{s ( s + 10 ) ( s + 100 )}

\frac{10 ( 12 - 15 )}{3}

a cos (b (x - c)) + d

\frac{( 2 ( 1 - cot ( 2 x ) ) ( sec ^{2} ( 2 x ) ) - 2 ( csc ^{2} ( 2 x ) ) ( tan ( 2 x ) ) )}{( 1 - cot ( 2 x ) ) ^{2}}

\frac{x ^{2} ( x + 1 ) ^{2}}{4}
