Answer:

$2y(x-1)(x^2+x+1)$

Step-by-step explanation:

$~~~2x^3y-2y\\\\=2y(x^3-1)\\\\=2y(x-1)(x^2+x+1)~~~~~~~~~~;[a^3-b^3 = (a-b)(a^2 +ab+b^2)]$

FAST!! Evaluate tan60/cos45<br> √6<br> √3/2<br> √2/3<br> 1√6

evablogger [386]

Answer:

$\frac{\tan 60\degree}{\cos45 \degree}= \sqrt{6}$

Step-by-step explanation:

We want to evaluate

$\frac{\tan 60\degree}{\cos45 \degree}$

We use special angles or the unit circle to obtain;

$\frac{\tan 60\degree}{\cos45 \degree}=\frac{\sqrt{3}}{\frac{\sqrt{2}}{2}}$

This implies that;

$\frac{\tan 60\degree}{\cos45 \degree}=\sqrt{3}\div \frac{\sqrt{2}}{2}$

$\frac{\tan 60\degree}{\cos45 \degree}=\sqrt{3}\times \sqrt{2}$

$\frac{\tan 60\degree}{\cos45 \degree}= \sqrt{6}$
