Use a calculator punch in the numbers
The correct answer is 20.
square root 2 times square root of 200 = square root of 400 ans since 400 is a perfect square, then I'll calculate to 20.
Well, your equation y=3/SQRT(3x+4) should be rationalized, but that's not what you want.
If f(x) = 3/SQRT(x+4) and g(x) = 3x
f(g(x)) then = 3/SQRT(3x+4), but rationalizing this = 3SQRT(3x+4)/(3x+4)
1/6 is the answer. Good luck!
