M and N are two subsets of the universal set (U). If n(U) = 48, n(M) = 20, n(N) = 30 and n(MUN) = 40, find n(M \(\cap\) N)

If \(\log_{10}\)(6x - 4) - \(\log_{10}\)2 = 1, solve for x.

If F = \(\frac{9}{5}\)C + 32, find C when F = 98.6

Simplify; 2\(\frac{1}{4} \times 3\frac{1}{2} \div 4 \frac{3}{8}\)

Simplify: \(\sqrt{108} + \sqrt{125} - \sqrt{75}\)

Given that y varies inversely as the square of x. If x = 3 when y = 100, find the equation connecting x and y.

Evaluate: \((64^{\frac{1}{2}} + 125^{\frac{1}{3}})^2\)
