type in "sqr 89875517873681764m/s"
and googles calculator displays the following
sqr(89875517873681764)(meters / second) = 299792458 m / s

Yes, it's only taking the square root of the number because it's following the usual convention of applying unary operators before multiplication. It clearly shows you that's what it's doing by inserting the brackets with the answer.

Square root the whole thing together and see what you get:

sqr (89875517873681764 m^2/s^2)

Then try that with your answer. It won't even solve.
