Question

Urgent! Vr sa fie corecta ca îmi pune nota pe ea. Va rog din suflet cât mai repede. Multumesc! ​

Answer 1

1.a.true&&true=true

b.false||false = false

c.true || !true = true

d.7/4+4/7 = 1 + 0 = 1

e.7 + 5 + 4 + 7 = 23

f.7 + 7 * 4 + 3 = 10 + 28 = 38

g.(7+7)*(4+3) = 14*7 = 98

h.7%4-4%7 = 3 - 4 = -1

i.4 - 4/3*3 = 4 - 1 * 3 = 4 - 3 = 1

2.a.n>=0&&n%2==0&&n/10==a&&n%10==b

b.n>=0&&n%10 != 0 && n%10 != 5

c.n == a%10

3.a.4*(27 - 5*(8-6))/2+11

b.8*((15-7)/2)

4.a.$\frac{a+b}{c} + \frac{2b + c}{2a+b}-\frac{3(a-b)}{2a-b}$

b.$\frac{a}{\frac{b+2c}{a+b+c}-a}+\frac{\frac{a}{b+c}}{\frac{c}{2a + 2c + b}}$

5.!(5+5<0)||(5+10>=5)&&!(10/3!=1)

=!(10<0)||(15>=5)&&!(3!=1)

=!false||true&&!true

=true||true&&false

=true && false

=false
