22. Evaluate the square root of xy when x=15 and y=15.
square root of 15(15)
=
square root of 225
=
15
?
I am not certain of your question.
If the question is
what is the sqrt(15*15), then the answer is indeed 15.
sqrt (a*a)= a
yes, that's what it is.
Thanks
To evaluate the square root of xy when x = 15 and y = 15, we can substitute the values of x and y into the expression and simplify.
First, we substitute x = 15 and y = 15 into the expression:
√(xy) = √(15 * 15)
Next, we simplify the expression inside the square root:
√(225)
Since 225 is a perfect square, we can take the square root:
√(225) = 15
Therefore, the square root of xy when x = 15 and y = 15 is 15.
