![]() This is very useful for long division test problems and was how mathematicians would calculate the square root of a number before calculators and computers were invented. √121 = 121 ½ How to Find the Square Root of 121 Using Long Divisionįinally, we can use the long division method to calculate the square root of 121. Let's see how to do that with the square root of 121: SQRT(121) = 11 What is the Square Root of 121 Written with an Exponent?Īll square root calculations can be converted to a number (called the base) with a fractional exponent. On a computer you can also calculate the square root of 121 using Excel, Numbers, or Google Sheets and the SQRT function, like so: √121 = 11 How to Calculate the Square Root of 121 with a Computer On most calculators you can do this by typing in 121 and then pressing the √x key. If you have a calculator then the simplest way to calculate the square root of 121 is to use that calculator. The 4th root of 81, or 81 radical 3, is written as 814 ☓ 81 4 ± 3. For complex or imaginary solutions use Simplify Radical Expressions Calculator. See additional notes associated with our square root calculator and cube root calculator. How to Calculate The Square Root of 121 with a Calculator This calculator will find the given root of real numbers. Since 121 is a perfect square it can be simplified because the result will always be equal to a whole number. Can the Square Root of 121 Be Simplified? We already know if 121 is a perfect square so we also can see that √121 is a rational number. If it's not a perfect square then it's an irrational number. Rational numbers can be written as a fraction and irrational numbers cannot.Ī quick way to check this is to see if 121 is a perfect square. Is The Square Root of 121 Rational or Irrational?Ī common question is to ask whether the square root of 121 is rational or irrational. ![]() To find out more about perfect squares, you can read about them and look at a list of 1000 of them in our What is a Perfect Square? article. In this case, as we will see in the calculations below, we can see that 121 is a perfect square. 10 years ago At 0:28, you added all the values and observed that if the sum was divisible by 3, so was the value. In math, we refer to 121 being a perfect square if the square root of 121 is a whole number. √121 = q × q = q 2 Is 121 a Perfect Square? Thus, for calculating the square root fraction following 99 6. Thus, for calculating the quotient of the following square roots 72 6 72 6, just enter simplifysurd ( 72 6 72 6) the result 2 3 2 3 is returned. Make all your math problems easier and faster with our site provided free online calculators for various mathematical & statistical concepts.So what is the square root? In this case, the square root of 121 is the quantity (which we will call q) that when multiplied by itself, will equal 121. The online square root calculator can symplify surds root quotients in exact form. You can choose any of the methods that you are comfortable with and do your computations.Įxample : Compute the Fractional Exponent 16 3/2? You need not bother about the order as you can split it into two parts. You just need to raise the number to the power n and take out the dth root from it. In the cases where the numerator is not equal to 1(n≠1) An exponent of 1/k is called as the k-th Root.įractional Exponents having the numerator other than 1(any fractions) The first one exponent of 1/2 is called the square root and the next one exponent of 1/3 is referred to as cube root. Let's check out Few Examples whose numerator is 1 and know what they are called. Fractional Exponents having the numerator other than 1(any fractions)įractional Exponents having the numerator 1įraction Exponents are a way of expressing powers along with roots in one notation.Fractional Exponents having the numerator 1.You can see all of them and know how to solve the fractional exponents with different conditions. There are several conditions while dealing with Fractional Exponents.
