Square Root Table

In mathematics, the square of a number refers to the value which we get after multiplying the same number by itself (Y x Y= X). In here, square root of of X (√X) refers to Y. Every non negative number such as 1,2,3,4,5,… etc can have a non negative square root such √4=2,√9=3,√16=4 etc

A square number such as 16 can have 4 and -4 as a square root because (4)2 =16 and (-4)2 =16 this means every square number can have positive and negative numbers as square root. But, we need to prefer non negative numbers in terms of square root. The square root table for first 10 square numbers are:

Every non negative number, if it is multiplied by itself, then the result is a square. From the above example,

2 x 2

4

3 x 3

9

4 x 4

16

5 x 5

25

6 x 6

36

7 x 7

49

8 x 8

64

9 x 9

81

10 x 10

100

11 x 11

121

Just like the formulas of mathematics helps us to solve complex problems. Having a square root table handy will prove to be useful while solving equations with speed and accuracy. Similar to the square root table, we have cube root table.

Cube root of a number is written as 3√A = B which means B x B x B = A. Cube root of a negative integer is always a negative integer which means 3√(-27)= (-3) i.e. (-3) x (-3) x (-3) = (-27).

Even having a cube root table at hand proves to be useful for complex arithmetic operations. Here, is the cube root table of first 10 cube numbers.

Knowing the square root and cube root table while learning the equations and formulas simultaneously will be helpful for achieving excellent scores in this subject.

Even today, the maths square root table is one of the most used on the web. By referring to the square and square root table we can solve this particular type of equation such as \(\large 5{^{2}} + \sqrt{16}= ?\)

And by referring to the square root and cube root table pdf you can solve complex problems such as \(\large \sqrt{121} – \sqrt[3]{64}= ?\)
