expand (5-2e^{4x})^2

expand

(5 - 2 e^{4 x})^{2}

25 - 20 e^{4 x} + 4 e^{8 x}

Solution steps

(5 - 2 e^{4 x})^{2}

Apply Perfect Square Formula:

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

a = 5, b = 2 e^{4 x}

= 5^{2} - 2 \cdot 5 \cdot 2 e^{4 x} + (2 e^{4 x})^{2}

Simplify

5^{2} - 2 \cdot 5 \cdot 2 e^{4 x} + (2 e^{4 x})^{2} : 25 - 20 e^{4 x} + 4 e^{8 x}

= 25 - 20 e^{4 x} + 4 e^{8 x}

100 + e^{((x + 30) \cdot 0.1)}

\frac{( x + 1 ) ( x + 2 )}{( x + 11 ) ( x - 2 )}

(- \frac{t}{100 π} + K)^{2}

lo g_{2} (b)

2 (10 a + 2 b = 10) 2
