(5 la puterea7 plus 5 la puterea 6 plus 5 la puterea 5):5 la puterea5 plus 9 la puterea7:3 la puterea10.
va rog cine stie. Va multumesc.

Answer 1

=5^7/5^5+5^6/5^5+5^5/5^5+3^2^7:3^10=
5^2+5^1+1+3^14:3^10=
25+5+1+3^4=
31+81=112

Answer 2

[tex](5^{7} + 5^{6} + 5^{5} ): 5^{5} + 9^{7} : 3^{10} = [/tex]
[tex] 5^{5} *( 5^{2} +5+1): 5^{5} +( 3^{2} ) ^{7} : 3^{10} = [/tex]
$25+5+1+ 3^{14} : 3^{10} =$
$31+ 3^{4} =31+81=112$
