Answer Show Verified Hint: In the given question, we need to find the square root of $1.8$ so we are asked to find the value of $\sqrt {1.8} $. We can find the square root of decimals by converting it into rational numbers. We can easily find this using a calculator but we are going to see a method to find the square root of any number. Complete step by step answer: Note: Answer Verified Hint: In the above problem, we are asked to find the square root of 145 and which we are going to find by dividing the number into two parts: the first part contains the first two numbers (145) and the second part contains the last two numbers (145). Then we will find a number by hit and trial whose square is lesser than or equal to the first number (i.e. 1). Then we subtract the square of the number obtained from hit and trial from the first number and write the remaining number. Remaining steps will be more clear in the below solution. Complete step by step answer: \[1\left| \begin{align} From the above long division method, we have come to a conclusion that the square root of 145 is 12.041. Note: You
can check whether the square root you have found is correct or not by multiplying the square root of 145 by itself and see if we are getting the same number which we have started with. What's the square root of a negative number?Negative numbers doesn't have real square roots since a square is either positive or 0.
Is the square root of a negative number positive or negative?Any number squared will produce a positive number, so there is no true square root of a negative number. Square roots of negative numbers can only be determined using the imaginary number called an iota, or i.
How do you find √?For example, 6 × 6 = 36. Here, 36 is the square of 6. The square root of a number is that factor of the number and when it is multiplied by itself the result is the original number. Now, if we want to find the square root of 36, that is, √36, we get the answer as, √36 = 6.
What is a square root of 256?Answer. Hence, the square root of 256 is 16.
