It is not feasible to discover such a whole number which on squaring gives 125It can be around written as a square of 11.180, i beg your pardon is a non-recurring and also non-terminating decimal number.This mirrors it isn"t a perfect square, which additionally proves that the square root of 125 is one irrational number.
How to discover the Square root of 125?
There are many methods to evaluate the square root of 125. Let us try the prime factorization and also the long department method here.
Square root of 125 by prime Factorization
To leveling the square root of 125, permit us first express 125 as a product the its prime factors. The element factorization of 125 is 5 × 5 × 5. The square root of 125 is 5 √5.
Square root of 125 by Long division MethodStep 1: Starting native the right, we will pair up the number by putting a bar above them.We will have two pairs, i.e., 1 and 25Step 2: We division the left-most number through the biggest number whose square is much less than or equal to the number in the left-most pair.Step 3: dual the divisor and also enter it with a blank on the right. Guess: v the largest possible digit to to fill the empty which will likewise become the brand-new digit in the quotient, such that once the new divisor is multiplied to the new quotient the product is much less than or same to the dividend. Divide and also write the remainder. Step 4: Repeat this procedure to gain the decimal places you want.
Thus √125 = 11.1803398875
