simplify √54
To simplify √54, we can look for perfect square factors of 54.
The prime factorization of 54 is 2*3*3*3, which can also be written as 2*3^3.
We can see that 3^2 = 9 is a perfect square factor of 54.
So, we can simplify √54 as follows:
√54 = √(2*3^2*3) = √(3^2 * 2*3) = √(3^2) * √(2*3) = 3√2√3
Therefore, the simplified form of √54 is 3√2√3.
