\(=\frac{\left(3.4.12^{16}\right)^2}{11.2^{13}.4^{11}-16^9}\)
\(=\frac{3^2.4^2.12^{32}}{11.2^{13}.2^{22}-2^{26}}\)
\(=\frac{3^2.2^4.2^{64}.3^{32}}{11.2^{35}-2^{26}}\)
\(=\frac{3^{34}.2^{68}}{2^{26}\left(11.2^9-1\right)}\)
\(=\frac{3^{34}.2^{42}}{11.2^9-1}\)
Còn lại làm típ nha :)
5 . 213 . 411 - 169 / ( 3 . 217)2
=5 . 213 . 222 - 236 / 32.234
=5 . 235 - 236 / 32.234
= 235. (5 - 2) / 32.234
= 235. 3 / 32.234
= 2/3
a,\(\frac{3^{10}.\left(-5\right)^{21}}{\left(-5\right)^{20}.3^{12}}=\frac{3^{10}.\left(-5\right).\left(-5\right)^{20}}{\left(-5\right)^{20}.3^{10}.3^2}\)\(=\frac{-5}{3^2}\)
b,\(\frac{-11^5.13^7}{11^5.13^8}=\frac{-11^5.13^7}{\left(-11\right)^5.\left(-1\right)^5.13^7.13}\)\(=\frac{1}{-1^5.13}\)
\(\frac{3^{10}.\left(-5\right)^{21}}{\cdot\left(-5\right)^{20}.3^{12}}=\frac{\left(-5\right)}{3^2}=\frac{-5}{9}\)
\(\frac{\left(-11\right)^5.13^7}{11^5.13^8}=\frac{-1}{13}\)
a ) 13 . 35 + 13 . 67 - 26
= 13 . ( 35 + 67 ) - 26
= 13 . 102 - 26
= 1326 - 26
= 1300
b) ( 25 .12 + 4 . 25 ) : 27
= [ 25 . ( 12 + 4 ) ] : 27
= 25 . 16 : 27
= 25 . 24 : 27
= 29 : 27
= 22 = 4
c) 23 . [ 50 - ( 17 - 54 : 33 )] + 16
= 8 . [ 50 - ( 17 - 54 : 27 )] + 16
= 8 . [ 50 - ( 17 - 2 )] + 16
= 8 . [ 50 - 15 ] + 16
= 8 . 35 + 16
= 280 + 16
= 296
