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.
