Evaluate the following
√720
Term 1 has a square root, so we evaluate and simplify:
Simplify √720.
Checking square roots, we see that
262 = 676 and 272 = 729
Our answer in decimal format is between 26 and 27
Our answer is not an integer
Simplify it into the product of an integer and a radical.
We do this by listing each product combo of 720
Check for integer square root values below:
√720 = √1√720
√720 = √2√360
√720 = √3√240
√720 = √4√180
√720 = √5√144
√720 = √6√120
√720 = √8√90
√720 = √9√80
√720 = √10√72
√720 = √12√60
√720 = √15√48
√720 = √16√45
√720 = √18√40
√720 = √20√36
√720 = √24√30
From that list, the highest factor with an integer square root is 144
Therefore, we use the product combo √720 = √144√5
Evaluating square roots, we see that √144 = 12
Simplifying our product of radicals, we get our answer:
Group square root terms for 12
12√5
Final Answer:
12√5
