Question

Calculați a) 2,1(3)• 3 supra 2 la puterea 5+ (1 supra 2- 1 supra 5) totul la puterea 2 • 2 la puterea a doua

Answer 1

2,1(3) x (3/2)⁵ + (1/2 - 1/5)² x 2² =
2 intregi (13-1)/90 x 243/32 + (3/10)² x 2² =
2 intregi 12/90 x 243/32 + 9/100 x 4 =
192/90 x 243/32 + 9/25 =
32/15 x 243/32 + 9/25 =
81 + 9/25 =
(81x25 + 9)/25 =
(2025+9)/25 =
2034/25 =
81,36
