3.873
The square root of 15 is 3.873.
Why is the square root of 16 is 4?
Expert Answers This is because the without a sign in front signifies the principal square root which is always positive. To signify both the positive and negative square roots we use which is equal to both +4 and -4.
Why is the sqrt of 4 not?
The value of root 4 is equal to exactly 2. But the roots could be positive or negative or we can say there are always two roots for any given number. Hence, root 4 is equal to ±2 or +2 and -2 (positive 2 and negative 2).

What is the square of 15 answer?
The Square of 15 is 225. You can get the answer with any other number with 5 at it’s once place.
What is the square root of 15 to the 4th power?
Think of this as sqrt (15)*sqrt (15)*sqrt (15)*sqrt (15) or sqrt (15) squared times sqrt (15) squared. sqrt (15) squared is 15; so we essentially have 15 squared which is 225. For those with more knowledge of mathematics sqrt (15) raised to the 4th power is equal to 15 raised to the 4/2 which is equal to 15 squared equals 225.
What are the uses of the sqrt function?
To understand the uses of the SQRT function, let’s consider a few examples: Suppose we wish to find the square root of the following numbers: The formula used would be =SQRT (reference). We will get the following results: If a number provided by a user is negative, the SQRT function will return the #NUM! error.
The value of root 4 is equal to exactly 2. But the roots could be positive or negative or we can say there are always two roots for any given number. Hence, root 4 is equal to ±2 or +2 and -2 (positive 2 and negative 2). You can also find square root on a calculator.
Why does the sqrt function return a negative number?
If a number provided by a user is negative, the SQRT function will return the #NUM! error. The square root of a negative number does not exist among the set of real numbers. It is because there is no way to square a number and get a negative result.
