Write √(-12) in simplest radical form

Mathematics
1 answer:
snow_lady [41]3 years ago
3 0

Answer:  2i\sqrt{3}

where i = \sqrt{-1}

====================================================

Work Shown:

x = \sqrt{-12}\\\\x = \sqrt{-1*4*3}\\\\x = \sqrt{-1}*\sqrt{4}*\sqrt{3}\\\\x = i*2*\sqrt{3}\\\\x = 2i\sqrt{3}\\\\

Therefore, \sqrt{-12} = 2i\sqrt{3}

------------

Explanation:

The basic steps are to factor the radicand such that we pull out the -1 and we also pull out the largest perfect square factor. That way we can then apply the rule \sqrt{A*B} = \sqrt{A}*\sqrt{B} to break up the root and simplify.

Find the remainder when 129 + 1924 is divided by 10.
ZanzabumX [31]
Hey!


Alright let's solve the first part of the equation which is  129 + 1924.  All we have to do is add it so we find the answer to it.

129 + 1924 = 2,053

Now the next step to solving this would be to simply divide it by 10.

2,053 ÷ 10 = 205 R.3

See the image below to see how it's done.

<em>So, this means that </em><span><em>when 129 + 1924 is divided by 10 is</em>  205 R. 3

Hope this helps!
