91 is a Prime number, so you have to use a calculator, but if you had a number such as 99 use this method: divide 99 by a number that goes into it evenly, such as 9, now you have 9 and 11, 11 is prime so you set it aside, leaving 9. now divide 9 by a number, 3 is the only one in this situation, so you have two 3's. once you only have prime numbers put them with likes, so now you have 3,3,11, all numbers that have a pair you take out one and cross off that pair, leaving those without under the radical (square root). in this case the answer is 3 multiplied by the square root of 11. in order to find the square root of any prime number, a calculator is required.
irrational
As 91 = 7 × 13, √91 doesn't really simplify. It can be changed into: √91 = √(7×13) = √7 √13
Each side is the square root of 91 meters, which is about 9.539392 meters.
Yes. It would be 21/2 * 91/2, or "three root two". Root two is an irrational number, so it's products - such as root 18, will be as well.
The square root SYMBOL is √ Occasionally it may have a superscript 2 to prevent any confusion with other types of roots.... ²√ Although not a Symbol, the square root can also be identified by using an index or power of ½. So, √9 = 3, ²√9 = 3 91/2 = 3............are three ways of showing that the square root of 9 is 3.
The square root of 91 is not a rational number. the best way to express that number is by using the term the square root of 91 or 91^1/2 or sqrt(91) The answer, then, is 9.539 (approx).
The square root of 8281 is 91.
The square root of 91 is an irrational number. This can be determined by showing that 91 is not a perfect square, meaning it cannot be expressed as the square of an integer. Since the square root of 91 cannot be simplified to a rational number, it is classified as irrational.
The square root of 91 is between 9 and 10

The four numbers are:3.0886,-3.0886,3.0886*i and-3.0886*iwhere i is the imaginary square root of -1.The first two roots are real numbers.
Yes. It would be 21/2 * 91/2, or "three root two". Root two is an irrational number, so it's products - such as root 18, will be as well.
