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

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:

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

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

8 x 10^-3 is how many times as great as 4 x 10^-6

mamaluj [8]

For this case we can rewrite the expressions as:

$3 * 10 ^ {- 3} = 0.003$

That is, we run the decimal three times to the left.

$4 * 10 ^ {- 6} = 0.000004$

That is, we run the decimal six times to the left.

So:

$0.003-0.000004 = 0.002996$

So, we have that $3 * 10 ^ {- 3}$ is 0.002996 times bigger than $4 * 10 ^ {- 6}$

Answer:

$3 * 10 ^ {- 3}$ is 0.002996 times bigger than $4 * 10 ^ {- 6}$
