\(-5^2-5\cdot32=5\left(5-32\right)=5\cdot\left(-27\right)=-135\)
\(4^6\cdot9^5+6^9\cdot120=241864704+1209323520=1451188224\)
(chả có cái đề nào ra kết quả như vày cả, có sai ko z?)
\(5^3+5^2\cdot3^2=125+25\cdot9=125+225=350\)
\(8^4\cdot3^{12}-6^{11}\)
\(=\left(2^3\right)^4\cdot3^{12}-6^{11}\)
\(=2^{12}\cdot3^{12}-6^{11}\)
\(=6^{12}-6^{11}\)
\(=6^{11}\cdot6-6^{11}\cdot1\)
\(=6^{11}\cdot5\)
