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. √49 = 49 ½ How to Find the Square Root of 49 Using Long Divisionįinally, we can use the long division method to calculate the square root of 49. 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. Let's see how to do that with the square root of 49: This calculator will find the given root of real numbers. SQRT(49) = 7 What is the Square Root of 49 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 49 using Excel, Numbers, or Google Sheets and the SQRT function, like so: √49 = 7 How to Calculate the Square Root of 49 with a Computer On most calculators you can do this by typing in 49 and then pressing the √x key. If you have a calculator then the simplest way to calculate the square root of 49 is to use that calculator. How to Calculate The Square Root of 49 with a Calculator Since 49 is a perfect square it can be simplified because the result will always be equal to a whole number. Converting between fractions and decimals: Converting from decimals to fractions is straightforward. In both cases, fractions are presented in their lowest forms by dividing both numerator and denominator by their greatest common factor. We already know if 49 is a perfect square so we also can see that √49 is a rational number. The calculator provided returns fraction inputs in both improper fraction form as well as mixed number form. 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 49 is a perfect square. Is The Square Root of 49 Rational or Irrational?Ī common question is to ask whether the square root of 49 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 49 is a perfect square. In math, we refer to 49 being a perfect square if the square root of 49 is a whole number. √49 = q × q = q 2 Is 49 a Perfect Square? The GCF of 45 and 10 is 5.So what is the square root? In this case, the square root of 49 is the quantity (which we will call q) that when multiplied by itself, will equal 49. This calculator reduces the improper fraction to lowest terms by dividing numerator and denominator by the greatest common factor ( GCF).When possible this calculator first reduces an improper fraction to lowest terms before finding the mixed number form.Įxample: Convert the improper fraction 45/10 to a mixed number. With 1 as the numerator and 3 as the denominator, the fraction part of the mixed number is 1/3. Divide 16 by 3: 16 ÷ 3 = 5 with remainder of 1.This is the fraction part of the mixed number.Įxample: Convert the improper fraction 16/3 to a mixed number. Use the remainder as the new numerator over the denominator.Divide the numerator by the denominator.How to Convert an Improper Fraction to a Mixed Number Examples of improper fractions are 16/3, 81/9, 525/71. The numerator must be greater than the denominator, (an improper fraction), so it can be converted to a mixed number.Īn improper fraction is any fraction where the numerator is greater than the denominator. A number that will divide evenly into both the numerator and denominator so it can be reduced, or. In order to simplify a fraction there must be: This calculator also simplifies proper fractions by reducing to lowest terms and showing the work involved. Convert improper fractions to mixed numbers in simplest form.
