Question

1) (15*3^13+4*27^5)/(17*9^7)

2) (7*2^78-9*2^77)/16^19
по действиям пожалуйста

Answer 1

1)
$\frac{15 \times {3}^{13} + 4 \times {3}^{15} }{17 \times {3}^{14} } = \\ = \frac{(15 + 4 \times {3}^{2}) \times {3}^{13} }{17 \times {3}^{14} } = \\ = \frac{15 + 4 \times 9}{17 \times 3} = \\ = \frac{15 + 36}{51} = \frac{51}{51} = 1$

2)
$\frac{(2 \times 7 - 9) \times 2 {}^{77} }{ {2}^{76} } = \\ = (14 - 9) \times 2 = 5 \times 2 = 10$
Ответ: 1) 1. 2) 10.
