Answer:

The answer is 156

Step-by-step explanation:

36(3) - 8y (-6) = 156

And just in case there is a 2 after 7, you would have to multiply by 2, so it would still equal 312.

QveST [7]

Answer: (6\sqrt{5})i

This is the same as saying 6i\sqrt{5}

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

Work Shown:

\sqrt{-180} = \sqrt{-1*36*5}\\\\\sqrt{-180} = \sqrt{-1}*\sqrt{36}*\sqrt{5}\\\\\sqrt{-180} = i*6*\sqrt{5}\\\\\sqrt{-180} = 6i\sqrt{5}\\\\\sqrt{-180} = (6\sqrt{5})i\\\\

where i = \sqrt{-1}

As the steps show above, the idea is to factor the radicand into smaller pieces where one of those pieces is the largest perfect square possible. In this case, 36 is the largest factor of 180 that's a perfect square. Then I used the rule \sqrt{A*B} = \sqrt{A}*\sqrt{B} to break up the root.

The parenthesis used at the very end is to help separate the 6\sqrt{5} from the i term. The "i" is not under the square root.

What is 1,766,655 rounded to the nearest hundred
Vesnalui [34]
655 rounded to the nearest hundred would be 700, so that could be an answer but some teachers say that you still have to keep the other digits. So it could be 700 or 1,766,700
