1 square root of 21 (1√21)

Here we will show you how to calculate 1 square root of 21, which is the same as 1√21, which again is the same as 1 times √21. In other words, we will calculate 1 × √21.

We will not only calculate the 1 square root of 21 decimal answer, but we will also calculate 1 square root of 21 simplified. We will start by calculating the decimal answer to 1 square root of 21, as follows:

1. Find the square root of 21:
√21 ≈ 4.582576

2. Multiply 1 by the square root of 21:
1 × 4.582576 = 4.582576

1√21 ≈ 4.582576

To get the answer to 1 square root of 21 simplified, we first determine if √21 can be simplified, and then we multiply what is outside the radical (√) by 1 to get 1 square root of 21 simplified.

√21 can be simplifed to 1√21. Therefore, 1 square root of 21 simplifed can be calculated like this:

1 × 1 × √21 = √21

1√21 simplified = √21
