The product of 2 √3 and 3 √12 simplified form is...

Serjik [45]

<h2>Greetings!</h2><h3>When multiplying two roots together, you can rearrange the equation so that the roots are next to each other and so are the whole numbers:</h3>

2 x 3 x $\sqrt{3}$ x $\sqrt{12}$

<h3>This means that 2 x 3 is simple, = 6,</h3><h3>But when multiplying $\sqrt{3} x \sqrt{12}$ you simply multply the two numbers and put them in a square root:</h3>

$\sqrt{3} x \sqrt{12}$ = $\sqrt{36}$

<h3>But this can be square rooted to 6, which then means that the equation is now:</h3>

2 x 3 x 6 = 36

<h3>So the simplified form is 36.</h3>
