An irrational number has a never-ending decimal expansion. To estimate it's value, you'd just state the expansion to some number of digits.
Ex:
sqrt(2) is approximately 1.4142135623730950488
pi is approximately 3.14159265358979323846

How do you estimate an irrational number Why might you need to be able to estimate an irrational number?
If you want to use a rational number for a mathematical operation, it will be necessary to estimate it for a numerical outcome. Irrational numbers can't be written out exactly.
How do you estimate an irrational number and why do you need for?
How an irrational number is estimated depends on the nature of the number. The reason for estimating them is that two of the most important numbers in mathematics: pi in geometry and e in calculus, are both irrational. Also, the diagonal of a unit square is of length sqrt(2), an irrational. Irrational numbers crop up everywhere: there are more irrational numbers than there are rational.
What is the sum of an rational number and irrational number?
An irrational number.
How do you I estimate the square root of irrational numbers?
The same way that you would for a rational number that is not a perfect square.
Which of the following numbers will produce an irrational number when added to?
When added to a rational number, any irrational number will produce an irrational number.also, when added to an irrational number, any rational number will produce an irrational number.

How do you estimate an irrational number?
The number of s.f or rounding off
Which point on the number line shows the best estimate of the irrational number 57?

What is the sum of an rational number and irrational number?
An irrational number.
Is an irrational number plus an irrational number rational?
No. The sum of an irrational number and any other [real] number is irrational.
The sum of a rational number and an irrational number is?
The sum of a rational and irrational number must be an irrational number.
Is 3.56 an irrational number?
No, 3.56 is not an irrational number. 3.56 is rational.
Whether a rational number multiplied by an irrational number gives an irrational number?
rational * irrational = irrational.
Is negative pi rational or irrational?
-Pi is irrational, because it does not terminate or repeat. Whenever you multiply an irrational number by a rational number (-1), the result is an irrational number.
How do you I estimate the square root of irrational numbers?
The same way that you would for a rational number that is not a perfect square.
What is a negative irrational number?
A negative irrational number can be thought of as an irrational number multiplied by -1, or an irrational number with a minus sign in front of it.
