Solve the equation 5x2 - 4x - 1 = 0
-1, 1/5
-1, -1/5
1, 1/5
1, -1/5
-1, 5
Correct answer is D
5x2 - 4x - 1 = 0
5x2 5x + x -1 = 0
5x(x - 1) + (x - 1) = 0
(5x + 1)(x -1) = 0
x = -1/5 or 1 = 0
Simplify \(\frac{8^{\frac{2}{3}}*27^{\frac{-1}{3}}}{64^{\frac{1}{3}}}\)
-3
\(\frac{1}{9}\)
\(\frac{1}{3}\)
\(\frac{27}{8}\)
4
Correct answer is C
\(\frac{8^{\frac{2}{3}}*27^{\frac{-1}{3}}}{64^{\frac{1}{3}}}\)
\(\frac{2^2*3^{-3}}{4} = 3^{-1} = \frac{1}{3}\)
