. Am nevoie de rezolvari complete.Rezolvati ecuatiile ​

Answer 1

Explicație pas cu pas:

b) x=3-4=-1

c)×= radical din 8=2 radical din 2

x=2 radical din 2

d)×=1/30

f)×=-1-0,3=-1,3

g)×=6•2=12

h)-×=5

×=-5

i)×=16^2=256

k)×= radical din 5

l)×=-(1/2):3/4=-(1/2)•4/3=-(2/3)

×=-(2/3)

m)×=-2:6=-(2/6)=-(1/3)

×=-(1/3)

n)×= radical din 12= 2 radical din 3

×= 2 radical din 3

o) -×=-6+3=3

×=3

p)×=3;-3[ deoarece 3^2=9 ; (-3)^2=9]

q)×=-(3/4):[-(1/6)]=3/4•6=9/2

×=9/2

r) ×=0,2•0,6=2/10•6/10=1/5•3/5=3/25

×=3/25
