simplify 1/(sqrt(n))*(((2)+1)^n)/(3^n)

simplify

\frac{1}{n} \cdot \frac{( ( 2 ) + 1 ) ^{n}}{3 ^{n}}

\frac{1}{n}

Solution steps

\frac{1}{n} \cdot \frac{( ( 2 ) + 1 ) ^{n}}{3 ^{n}}

Apply rule:

(a) = a

(2) = 2

= \frac{1}{n} \cdot \frac{( 2 + 1 ) ^{n}}{3 ^{n}}

Cancel

\frac{( 2 + 1 ) ^{n}}{3 ^{n}} : 1

= \frac{1}{n} \cdot 1

Apply rule:

a \cdot 1 = a

= \frac{1}{n}

1 e^{- 2}

e^{- 6 t} sin (7 π t)

3.7 \cdot 1 0^{- 2}

7 x^{2} y^{5} (9 x^{3} y)

(3 yz) (6 y z^{3})
