Question

pls solve this mental maths

Answer 1

here is the answer .

Answer 2

Solution :-

a²ⁿ⁻³ × (a²)ⁿ⁺¹/(a⁴)⁻³ = (a³)³ ÷ (a⁶)⁻³

a²ⁿ⁻³⁺²ⁿ⁺²/a⁻¹² = a⁹/a⁻¹⁸

a⁴ⁿ⁻¹/a⁻¹² = a⁹⁻⁽⁻¹⁸⁾

a⁴ⁿ⁻¹/a⁻¹² = a⁹⁺¹⁸

a⁴ⁿ⁻¹/a⁻¹² = a²⁷

a⁴ⁿ⁻¹⁻⁽⁻¹²⁾ = a²⁷

a⁴ⁿ⁻¹⁺¹² = a²⁷

a⁴ⁿ⁺¹¹ = a²⁷

4n + 11 = 27

4n = 27 - 11

4n = 16

n = 16/4

n = 4
