gaseste"valoarea"literelor:a*a=100;c*c*10=250;p*p=p+p

Answer 1

[tex]a\cdot a=100\\ a^2=100\\ |a|=10\Rightarrow \boxed{a\in \{\pm 10\}}\\ \\ c\cdot c\cdot 10=250\\ c^2=5\\ |c|=25\Rightarrow \boxed{c\in \{\pm 5\}}\\ \\ p\cdot p=p+p\\ p^2=2p\\ p^2-2p=0\\ p(p-2)=0\Rightarrow \boxed{p\in \{0;2\}}[/tex]
