Question

va rog mult mult de tot

Answer 1

3)a)
= 10 + 36 - 35-11
= 0
b))
2017-{[42-(25x14-85x4)x2]X3 +2^6}
= 2017-{[42-(350-340)x2]x3+ 64}
= 2017-[(42-10x2)x 3 +64]
= 2017 -(22x3+64)
= 2017-(66+64)
= 2017- 130= 1887

C))
= (100 -49+625 )x (1+1)
= 676x 2 = 1352
4))
2^10- 2^11 :2
= 2^10 -2^10 = 2^0 = 1
5))
= 3^100: (3^48:3)
= 3^100:3^47
= 3^53
