Evaluate: (0.064)\(^{-\frac{1}{3}}\) 

Solve: \(\frac{y + 1}{2} - \frac{2y - 1}{3}\) = 4

Simplify, correct to three significant figures, (27.63)\(^2\) - (12.37)\(^2\) 

If 7 + y = 4 (mod 8), find the least value of y, 10 \(\leq y \leq 30\) 

If T = {prime numbers} and M = {odd numbers} are subsets of \(\mu\)  = {x : 0 < x ≤ 10} and x is an integer, find (T\(^{\prime}\) n M\(^{\prime}\)).
