What is the square root of 27?
1 answer(s)
The number 27 is not a perfect square. So the answer is not a simple whole number like 4 or 5. To find the exact answer, you must simplify it.
You can think of what numbers make 27. It is 9 times 3. We know the square root of 9 is 3. This is easy. So, you can take the 3 outside of the square root symbol. The other 3 must stay inside.
So the most exact answer is 3√3.
If you need this as a decimal for your homework, it is an irrational number. The numbers go on forever. On a calculator, the answer is approximately 5.196. I hope this is a help for you.
