Answer :
Estimation of [tex]\sqrt{18}[/tex] to nearest integer is 4.
For every two same numbers multiplied inside the square root, one number can be taken out of the square root.
For every three same numbers multiplied inside the cube root, one number can be taken out of the cube root. The same procedure can be followed for fourth root and more.
Perfect squares are numbers that are the products of integers by themselves. In other words, when an integer is multiplied by itself, the resulting product is termed as a perfect square of the given number. For example, 36 is a perfect square because it is the product of 6 by itself.
[tex]\sqrt{18}[/tex] is not a perfect square.
nearest to 18 , 16 and 25 are the perfect squares
So, [tex]\sqrt{18}[/tex] lies in between [tex]\sqrt{16}[/tex] and [tex]\sqrt{25}[/tex] .
[tex]\sqrt{18}[/tex] lies in between 4 and 5.
Nearest integer is 4.
So , estimation of [tex]\sqrt{18}[/tex] to nearest integer is 4.
