`(7^65 .23+7^65 .26)/7^64 -6^2 . 5`
`=[7^65 (23+26)]/7^64-36.5`
`=(7^65 . 7^2)/7^64-180`
`=7^3-180`
`=343-180`
`=163`
Đáp án:
` (7^{65}.23 + 7^{65}.26) : 7^{64} – 6^2.5`
` = [7^{65}. (23+26)] : 7^64 – 6^2.5`
` = (7^{65}. (23+26))/(7^{64}) – 6^2.5`
` = 7.(23+26) – 6^2.5`
` = 7.49 – 6^2.5`
` = 343 – 180`
` = 163`
