Q: The square root of 81 is how much less than 7 squared?

Write your answer...

Huh? The square root of 49 is 7. 4 squared is 16 Take it from there

4 squared is 16 The square root of 4 is 2 Hence, 4 squared is 14 greater than the square root of 4.

The square root of 324 is 18. Do you mean the square root? Or do you mean the root of 324, squared? If you do, and by "root" you mean "square root", then 324.

The square root of A2 is... A !

The square root of 28 minus the squared root of 7 =±2.64575131

Any square root squared is the number inside the ()

The square root of 81 squared is 81.

2

No.

Squared. E.g the square root of 4 is 2, and 2 squared is 4.

If a is any number, then a squared = (-a) squared, so one might say that a and -a are both square roots of a squared. However, the square root symbol always means the positive square root.

the squared root

The square root of meter squared is meter.

The square of any square root is equal to the number itself. For example, the square of the square root of 2 squared is equal to 2. The square root of 10 squared is equal to 10.Similarly, the square of the square root of 2 is equal to 2.

The square root of 5 squared is 5, which is a rational number.

[square root (78)] squared = 78. There is not a surd from for an integer.

Do you mean: What is the square root of (8 squared)? If so, there are two answers: 8 and -8. Or do you mean: What is the (square root of 8) squared? If so, there is only one answer: 8.

it is 18 because when you put all the numbers back into the square root it becomes the square root of 18 and the square root of 18 squared would be 18

It's the square root of a2+b2. It cannot be simplified. It is NOT a+b. The answer is c square.

-7.. square root cancels out square

Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.

A square root is a number which multipled by itself equals the number in question. The square root of 9 is 3, much like 3 squared is 9.

b over the square root of 5 The square root of 5b squared is 5b, and the simplified form of the square root of 125 is 5 root 5. The 5s then cancel out leaving b over the square root of 5.

The square root of 5 is closer to 2. 2 squared is 4 and 3 squared is 9. 4 is much closer to 5 than 9.
