Question

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

Punctul 6

Answer 1

a)5^4:5^2+5*(55^1-x:5)=5^3

5^2 + 5*55 - x = 5^3

25 + 275 - x = 125

25 + 275 - 125 = x

175 = x

b) (5^4)^14:25^12-5*(55^1+x:5)=5^2

5^56:5^24 - 5*55 + x = 25

5^32 - 5*55 -25 = -x

5(5^31-55-5)  = -x
