Question

Qual e o valor da expressão? $3^{2} -6^{2} =$$(10^{0} +10^{1} + 10^{2} )$ $(7^{2} )^{5} :(7^{3} ) ^{2} =$

Answer 1

$3^{2} -6^{2} \to~~9 - 36 \to~~ -27 \\\\\\(10^{0} +10^{1} + 10^{2} ) \to~~ 1+10+100\to~~111\\\\\\ (7^{2} )^{5} :(7^{3} ) ^{2} \to~~7^{2.5}:7^{3.2}\to~~ 7^{10}:7^6\to~~ 7^{10-6}\to~~ 7^4\to~~2401$
