Square root of 81. Step 1 divide the number into 2 parts the last 2 digits separate from the remaining number. 17122020 Now simplify this equation to estimate the square root to the nearest integer.

81 3 x 3 x 3 x 3. 625 5 x 5 x 5 x 5. Then put a bar over it as when doing long division.

We get 33 64. As 146 is way closer to 144 than 169 its estimate square root integer will be 12. The square root of a number is the value such thatwhen a number multiplied by itselffor example 3 x 3 9 3 is square root of 9.

See the numbers whose square has 4 in the units place ie. Cube root of 474552 will be 78. Find the cube root of 250047.

05112019 The Reciprocal of the root can be calculated by removing the second n from the third line.
