\(\left(7.3^5-3^4+3^6\right):3^4\)
\(\Leftrightarrow\left(7.243-81+729\right):81\)
\(\Leftrightarrow2349:81\)
\(\Leftrightarrow29\)
\(\left(7.3^5-3^4+3^6\right)\div3^4\)
\(\Leftrightarrow\left(7.243-81+729\right)\div81\)
\(\Leftrightarrow2349\div81\)
\(\Leftrightarrow29\)
Đúng thì xin để lại một l - i - k - e nhé
