Solve four equations, including two exponential ones and a fraction equation needing an LCD and a restriction, then write a power sum in the form a·bˣ with prime bases. Solve a compound inequality and give the answer in interval notation, place √38 between two consecutive integers without a calculator, solve a simultaneous-equation word problem about the cost of exercise books and pens, and find x + y given x² + y² = 28 and xy = 4.
