Online Square Root of 9 Tutors

Online Square Root of 9 Tutors Square root of a number is represented by a square root radical sign . The square root of a number can be calculated by simplifying the radical by writing the numbers prime factors. In order to find the square root of 9, we split 9 into its prime factors which is 3 * 3. Hence 9 = (3 * 3) = 3. 9 is called as the perfect square since its square root gives a perfect number instead of a radical or decimal number. Example 1: What is the value of the expression, 16 + 9? Here each square root radical should be simplified further. 16= (2 * 2 * 2 * 2). Now pull out the number which is repeating twice inside the radical. This gives: 16= 2 * 2 = 4 And 9 = 3. So, 16 + 9 = 4 + 3 = 7. Hence the simplified form of the expression 16 + 9 is = 7. Example 2: What is the value of the expression, 25 - 9? Here each square root radical should be simplified further. 25= (5 * 5). Now pull out the number which is repeating twice inside the radical. This gives: 25 = 5 And 9 = 3. So, 25 + 9 = 5 - 3 = 2. Hence the simplified form of the expression 25 - 9 is = 2.
