Question

Rezolvati ecuatiile 2+2 la puterea 2+x=2 la puterea 3+2 la puterea 2

5 la puterea2-x=5

3 la puterea2•×+3=3 la puterea3+x

7 la puterea 0(x-2 la puterea 5)=2 la puterea0

Answer 1

5^2-x=5 2-x=1 2+1=x,x=3 2+2^2+×=2^3+2^2 2^3+x=2^5 3+x=5,x=5-3,x=2 3^2x+3=3^3+x 3^2x+1=3^3+x 2x+1=3+x 2x-x=3-1 X=2
