What is the answer of square root of -24 in complex numbers

Sergio039 [100]

With $\sqrt{-1}=i$ , we have

$\sqrt{-24}=\sqrt{(-1)(24)}=\sqrt{-1}\sqrt{24}=i\sqrt{24}$

Since $24=2^3\cdot3$ , we can further write this as

$i\sqrt{24}=i\sqrt{2^2\cdot6}=2i\sqrt6$

Factor. m2 + 12m+36

Art [367]

<h3>Answer: Choice A which is (m+6)^2</h3>

Explanation:

Think of two numbers that multiply to 36 and add to 12. Those two numbers are 6 and 6

6+6 = 12

6*6 = 36

So we can factor it into (m+6)(m+6). Use the FOIL rule to expand it out to get m^2+12m+36 back again.

The expression (m+6)(m+6) is the same as (m+6)^2

If there are 5 different shaped erasers and 8 of each, you would have to multiply $5x8$ which equals 40. If there are 4 people in the group, 40 divided by 10 equals 4.
