Question

3-5 ×3²÷3-6 +(2²×3)²+(2/3)-¹+2-¹+(1/19)-¹​

Answer 1

Solution :-

→ 3-5 ×3²÷3-6 +(2²×3)²+(2/3)-¹+2-¹+(1/19)-¹

→ 3 - 5 * (9/3) - 6 + (4*3)² + (2/3)-¹+2-¹+(1/19)-¹

→ 3 - 15 - 6 + 144 + (2/3)-¹+2-¹+(1/19)-¹

→ 147 - 21 + (2/3)-¹+2-¹+(1/19)-¹

→ 126 + (2/3)-¹+2-¹+(1/19)-¹

now, using (a/b)^(-1) = (b/a)

→ 126 + (3/2) + (1/2) + 19

→ 126 + 19 + (3 + 1)/2

→ 145 + 2

→ 147 (Ans.)
