First, let's ask ourselves which square roots can be simplified. To answer it, you need to take the number which is after the square root symbol and find its factors. If any of its factors are square numbers (4, 9, 16, 25, 36, 49, 64 and so on), then you can simplify the sq...
We know that the value of the square root of 81 is 9. Now, substitute the value in the above-given expression, we get √81 +9 = 9+9 √81+9 = 18. Hence, the simplified form of √81 +9 is 18. Example 2: Find the value of k, if 2√81 + k = 28. ...
