Question 736279: a walkway forns the diagonal od a square playground. The walkway is 24m long. To the nearest tenth of a meter, how long is a side of the playground?
I did:
x ^2 + x^2 = 24^2
x^4 = 576
x= 4.89 m
but then x^2+x^2 does not equal 24^2
plus the book says the answer is 17 m

You can put this solution on YOUR website!
Your second step is the mistake. Try again: x%5E2%2Bx%5E2+=+what?
The variables, not the constant. Something about bases and exponents?...
