How do you do the square root of 7?

The Newton - Raphson method of successive approximations is easily implemented on a computer. You make a guess, test it by squaring it and compare it with the original target. JCF


What are radical terms?

A "radical" equation is an equation in which at least one variable expression is stuck inside a radical, usually a square root. The "radical" in "radical equations" can be any root, whether a square root, a cube root, or some other root. Most of the examples in what follows use square roots as the radical, but (warning!) you should not be surprised to see an occasional cube root or fourth root in your homework or on a test.


What is the greatest prime you must consider to test whether 854 is a prime number?

You only need to test numbers up to the last prime number equal to or less than the square root of a number when testing whether it is prime. The square root of 854 is between 29 and 30, so you would test up to the prime number 29.


How do you figure out prime numbers?

You try if the number is divisible by any smaller number (except one). If it isn't, it is a prime number. In practice, it is enough to test divisibility by factors up to the square root of the number.You try if the number is divisible by any smaller number (except one). If it isn't, it is a prime number.

Why do we test only the prime numbers less than the square root of the given number?

First, you do not. You must also test the square root of the given number. So the question should be in terms of "less than or equal to". Suppose you wish to test the number n and suppose s is the square root of n. Then s*s = n Now suppose p is factor of n, with factor pair q. so that n = p*q and, without loss of generality, assume that p ≤ q. Thus p*q = s*s so that p ≤ s ≤ q That is to say, one of the pair of factors of n will be less or equal to its square root while the other member of the factor pair will be greater or equal to the square root.

Is this true or false A square root is a number that has an integer square root?

THE ANSWER IS TRUE!!! I know this for a fact I took the test with this question in it so your welcome


How do you find the square root of 484?

Deductive reasoning. You know that the square root of 484 will be between 20 and 30, closer to 20. You know that numbers ending in 2 will create a product ending in 4. You test 22. It works. Everyone is happy.
