expand (2+e^{2x})^2

expand

(2 + e^{2 x})^{2}

4 + 4 e^{2 x} + e^{4 x}

Solution steps

(2 + e^{2 x})^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

a = 2, b = e^{2 x}

= 2^{2} + 2 \cdot 2 e^{2 x} + (e^{2 x})^{2}

Simplify

2^{2} + 2 \cdot 2 e^{2 x} + (e^{2 x})^{2} : 4 + 4 e^{2 x} + e^{4 x}

= 4 + 4 e^{2 x} + e^{4 x}

(0.4 + 0.6 e^{t})^{3}

e^{t} (H (t) - H (t - 1))

\frac{\partial}{\partial x} ((u) (3 x (x - 1)))

(5, 6, 8) - (7 i + 6 j)

2 x + y (cos (t)) + (2 y + x) e^{t}
