How do you simplify the square root of 44?

1 AnswerThe answer is 2√11 . To simplify a square root, you factor what’s inside the root into perfect squares and everything else. In this case, you can factor 44. … √44=√4⋅11. 4 is a perfect square, so you can take it out its root giving you the answer:2√11. 11 is a prime number meaning you cannot factor it any further.

Is 45 a perfect cube?

The value of cube root of one is 45. The nearest previous perfect cube is 27 and the nearest next perfect cube is 64 . Cube root of 45 can be represented as 3√45.

What is the radical expression of 45?

Since radical 45 is equal to radical 9 times radical 5, and because radical 9 is equal to 3 (since 9 is a perfect square), we can simplify radical 45 to 3 times radical 5 (see the diagram below for a more detailed look on how to simplify square roots).

Is 18 a perfect square?

Is 18 a perfect square number? A number is a perfect square (or a square number) if its square root is an integer; that is to say, it is the product of an integer with itself. Here, the square root of 18 is about 4.243. Thus, the square root of 18 is not an integer, and therefore 18 is not a square number.
