`(3^5 * 3^7)/(3^11)`
`= (3^(5+7))/(3^11)`
`= (3^12)/(3^11)`
`=3`
\(\dfrac{3^5\cdot3^7}{3^{11}}\)
\(=\dfrac{3^{5+7}}{3^{11}}\)
\(=\dfrac{3^{12}}{3^{11}}\)
\(=3^{12-11}\)
\(=3\)
\(\dfrac{3^5.3^7}{3^{11}}=\dfrac{3^{5+7}}{3^{11}}=\dfrac{3^{12}}{3^{11}}\)
Nếu đúng thì tick mk nha bn!
\(\dfrac{3^5.3^7}{3^{11}}=\dfrac{3^{12}}{3^{11}}=3\)
