√100以上 f(x y)=log(x^2 y^2) 128053-F(x y)=log(x^2+y^2)
Log b x = y with b being the base, x being a real number, and y being an exponent For example, 2 3 = 8 ⇒ log 2 8 = 3 (the logarithm of 8 to base 2 is equal to 3, because 2 3 = 8) Similarly, log 2 64 = 6, because 2 6 = 64 Therefore, it is obvious that logarithm operation is an inverse one to exponentiation 2 1 2 2 2 3 2 4 2 5 2 6 2 4 8 16 32 64 log 2 2 = 1 log 2 4 = 2 log 2Yes, the computation is wrong, the logarithm is missing, the correct derivative would be f'(z) = \frac{xiy}{x^2y^2} \quad \left(\;Im neuen Schwätz Werde MatheMillionär!
