simplify-2(-2^{N/2}+1)

simplify

- 2 (- 2^{\frac{N}{2}} + 1)

2 \cdot 2^{\frac{N}{2}} - 2

Solution steps

- 2 (- 2^{\frac{N}{2}} + 1)

Apply the distributive law:

a (b + c) = ab + a c

- 2 (- 2^{\frac{N}{2}} + 1) = - 2 (- 2^{\frac{N}{2}}) - 2 \cdot 1

= - 2 (- 2^{\frac{N}{2}}) - 2 \cdot 1

- 2 (- 2^{\frac{N}{2}}) = 2 \cdot 2^{\frac{N}{2}}

2 \cdot 1 = 2

= 2 \cdot 2^{\frac{N}{2}} - 2

cos (\frac{3 π}{4} - \frac{5 π}{4})

sin^{3} (2 x) (5 x + 3)^{7}

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

\frac{1}{( s - y ) ^{2}}

(x - \frac{1}{2})^{2} - \frac{81}{4}
