Question

5 la puterea 4 : 5 la puterea 2 + 5 x (55 - x : 5 ) = 5 la puterea 3 repede va rog!!

Answer 1

Explicație pas cu pas:

5^4:5^2+5x(55-x:5)=5^3

5^4-2+5x(55-x:5)=125

5^2+5x(55-x:5)=125

25+5x(55-x:5)=125

5x(55-x:5)=125-25

5x(55-x:5)=100

55-x:5=100:5

55-x:5=20

x:5=20+55

x:5=75

x=75:5

x=15

Coroană?

Answer 2

Răspuns:

5⁴÷5²+5×(55-x÷5)=5³

= 5²+5×55-⅕x=125

= 25+275-x=125

= 300-x=125

= -x = 125-300

=-x = -175|×(-1)

x= 175
