Evaluate the following
√247
Term 1 has a square root, so we evaluate and simplify:
Simplify √247.
Checking square roots, we see that
152 = 225 and 162 = 256
Our answer in decimal format is between 15 and 16
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 247
Check for integer square root values below:
√247 = √1√247
√247 = √13√19
From that list, the highest factor with an integer square root is 1
Therefore, we use the product combo √247 = √1√247
Evaluating square roots, we see that √1 = 1
Since 1 is the greatest common factor, this square root cannot be simplified any further:
Multiply by our constant of 1
Group square root terms for 1
1√247
Final Answer:
1√247
