Question

Simplify: 

10a³b⁹ / 5a²b⁸

This question was previously asked in
UPTET 2026 Paper 2 Social Studies Question Paper (3-Jul-2026) (Shift 1)
The correct answer is

2ab

Divide the numerical coefficients: \(10 \div 5 = 2\).

Divide the powers of a using the law \(a^m/a^n = a^{m-n}\): \(a^3/a^2 = a\), and similarly \(b^9/b^8 = b\).

Combining these gives \(2ab\).
