\(=\dfrac{7^{16}\cdot2^{16}\cdot7^{32}\cdot3^{32}\cdot7^{48}\cdot5^{48}}{5^{16}\cdot2^{16}\cdot5^{32}\cdot3^{32}\cdot7^{96}}\)
\(=\dfrac{7^{96}\cdot2^{16}\cdot3^{32}\cdot5^{48}}{7^{96}\cdot2^{48}\cdot5^{48}}=\dfrac{3^{32}}{2^{32}}=1.5^{32}\)

a) 64 - 4 x 6 - 48
= 4 x 16 - 4 x 6 - 48
= 4 x (16 - 6) - 48
= 4 x 10 - 48
= 40 - 48
= -8
b) 96 - 32 : 4 - 49
= 96 - 8 - 49
= 39

Tính
a )
64 - 4 x 6 - 48
= 64 - 24 - 48
= 40 - 48
= -8
b )
96 - 32 : 4 - 49
= 96 - 8 - 49
= 88- 49
=39
tk mk nha

a ) 62 - 4 x 6 + 48 b ) 96 - 32 : 4 - 49
= 62 - 24 + 48 = 96 - 8 - 49
= 38 + 48 = 86 - 49
= 86 = 37
ai thấy đúng thì tk mk nha

Ta có: 96 = 3.25
160 = 5.25
192 = 3.26
ƯCLN(96;160;192) = 25 = 32
Chọn (C) 32.

A = \(\dfrac{8\times12\times32+4\times27\times24+96\times41}{16\times48-48\times9+4\times3\times12}\)
A = \(\dfrac{96\times32+96\times27+96\times41}{16\times48-48\times9+48\times3}\)
A = \(\dfrac{96\times\left(32+27+41\right)}{48\times\left(16-9+3\right)}\)
A = \(\dfrac{96\times100}{48\times10}\)
A = \(\dfrac{20}{1}\) \(\times\) \(\dfrac{48\times10}{48\times10}\)
A = 20
