Question

(5^7 + 5^6 + 5^5):5^5 + 9^7 :3^10

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

$( {5}^{7} + {5}^{6} + {5}^{5} ) \div {5}^{5} + {9}^{7} \div {3}^{10} =$

${5}^{2} + {5}^{1} + {5}^{0} + ( {3}^{2} ) ^{7} \div {3}^{10}$

$25 + 5 + 1 + {3}^{4} = 31 + 81 =$

$= 112$
