Enter radical expression

Simplify √80.

Checking square roots, we see that 8² = 64 and 9² = 81.
Our answer is not an integer.
Simplify it into the product of an integer and a radical.

List each product combo of 80
checking for integer square root values below:
√80 = √1√80
√80 = √2√40
√80 = √4√20
√80 = √5√16
√80 = √8√10

From that list, the highest factor that has an integer square root is 16.
Therefore, we use the product combo √80 = √16√5
Evaluating square roots, we see that √16 = 4
