$\displaystyle\\Answer:\ x=\sqrt{2}\ \ \ \ \ x=-\sqrt{2}\ \ \ \ \ x=\frac{ln5}{2}$

Step-by-step explanation:

$5x^2-x^2e^{2x}+2e^{2x}=10$

$Let:\ x^2=t \ \ \ \ \ e^{2x}=v\\Hence,\\5t-tv+2v^2=10\\5t-tv+2v^2-10=10-10\\5t-tv-10+2v^2=0\\t(5-v)-2(5-v)=0\\(5-v)(t-2)=0\\5-v=0\\5-v+v=0+v\\5=v\\5=e^{2x}$

Prologarithmize both parts of the equation:

$ln5=lne^{2x}\\ln5=2x*lne\\ln5=2x*1\\ln5=2x\\$

Divide both parts of the equation by 2:

$\displaystyle\\x=\frac{ln5}{2}$

$t-2=0\\t-2+2=0+2\\t=2\\x^2=2\\x=\sqrt{2} \\x=-\sqrt{2}$

Solve the inequality. 3x + 5 ———- <4 2 x < [?]

astra-53 [7]

Answer:

$x \leqslant 1$

Step-by-step explanation:

first multiply both side by 2 to get rid of the fraction

$3x + 5 \leqslant 4(2)$

$3x + 5 \leqslant 8$

$3x \leqslant 8 - 5$

$3x \leqslant 3$

$x \leqslant 1$

What is the common denominator of 1/a + 1/b in the complex fraction (1/a - 1/b)/(1/a + 1/b)?

mezya [45]

For this case we have the following fraction:

$\frac{\frac{1}{a} - \frac{1}{b}}{\frac{1}{a}+\frac{1}{b}}$

To find the common denominator, what we must do is rewrite the fraction.

For this, we subtract fractions in the numerator and the sum of fractions in the denominator.

We have then:

$\frac{\frac{b-a}{ab}}{\frac{b+a}{ab}}$

We observe that the common denominator is given by the product:

$ab$

Answer:

the common denominator is:

D)ab
