Question

√2= ?. expain the answer clearly step by step plzzz​

Answer 1

Solution:-

1.41421356237

root of a number A is a number which when multiplied by itself is equal to the number A

if y = x*x

then, x is called the root of y. or √y=x

eg: √25=5

√81= 9

√64=8

√49=7

The above examples are called perfect squares because they can be expressed as the product of two equal integers

√2 is not a perfect square because the value needed to be squared is not an integer i.e. 1.41421356237 is a decimal.

another example of a non perfect square is √3

its value is 1.73205080757 which is not an integer thus √3 is not a perfect square.

Another thing you should know is complex numbers or (as they are denoted) i

i is any number whose square is negative, x*x=-y

which in practical ways is not possible

-5^2= +25

+5^2= +25
