Simplify √243

Simplify √243.

Checking square roots, we see that 152 = 225 and 162 = 256.
Our answer is not an integer.
Simplify it into the product of an integer and a radical.

List each product combo of 243
checking for integer square root values below:

243 = √1243
243 = √381
243 = √927

From that list, the highest factor that has an integer square root is 81.
Therefore, we use the product combo √243 = √813
Evaluating square roots, we see that √81 = 9

Simplify our product

243 = 9√3

Therefore, we can factor out 9 from the radical, and leave 3 under the radical

We can factor out the following portion using the highest even powers of variables:

= =
Our leftover piece under the radical becomes 9√3
Our final answer is the factored out piece and the expression under the radical
9√3
