Question

aflati pe x din ;5^4:5^2+5*(55^1-x)=5^3 ,(5^2)^14:25^12-5*(55^1+x:5)=5^2

Answer 1

Răspuns:

5⁴:5²+5(55¹-x)=5³

5(55-x)=5³-5²  /:5

55-x=5²-5

-x=25-5-55

x=55-20

x=35

(5²)¹⁴:25¹²-5(55¹+x:5)=5²

25¹⁴:25¹²-5(55+x:5)=25

-5(55+x:5)=25-25²  /(-1)

5(55+x:5)=5⁴-5²  /:5

55+x:5=5³-5

x:5=5³-5-55

x:5=5³-60

x=(125-60)*5

x=625-300

x=325
