Deriving Sizing Factors in Solar Array Reports

In a clean energy design firm, a drafting technician preparing a solar array installation report encounters an efficiency scaling factor of (34)2\left(\frac{3}{4}\right)^{-2}. To ensure the technical documentation is clear and easy to audit, you must write a short explanation demonstrating why this factor mathematically simplifies to (43)2\left(\frac{4}{3}\right)^2. Write an essay outlining the complete, step-by-step mathematical derivation of (34)2\left(\frac{3}{4}\right)^{-2} to (43)2\left(\frac{4}{3}\right)^2. Your response must recall and describe each of the four distinct mathematical steps of the derivation, identifying the exponent definitions and division rules applied at each step.
