Question

Va rog repede am nevoie in 5 minute dau coroana va rogggggggg rapiiiiidddd​

Answer 1

a) x= 3 + 3- (3^18:3^17) x (2^30:2^30)

x= 3+3-3x3^0

x=3+3-3

x=3

y=3 x(5+2x3-2430:405)

y=3x(5+6-6)

y=3x5

y= 15

b) 3+15= 18

15-3=12

(3^15):(3^2)^7

(3^15):(3^14)=3

c) 15 : 2 = 7 + 1

7 : 2 = 3 + 1

3 : 2 = 1 + 1

1 : 2 = 0 + 1

15(baza10) = 1111(baza2)

Sper că te-am ajutat!
