Lời giải và giải thích chi tiết:
[23. 5^{22} . (-5)^12 + (-26) . (-5)^30 . (-625) ]
= 23. 5^{22} . 5^{12} + 26 . 5^{30} . 5^4
= 23. 5^{34} + 26 . 5^{34}
= 5^34 . (23 + 26)
= 5^34 . 49
[ 23. 5^{22}. ( -5 )^{12} + ( -26 ). ( -5 )^{30}. ( -625 ) ]
= [ 23. 5^{22}. 5^{12} + 26. 5^{30}. 5^4 ]
= [ 23. 5^{34} + 26. 5^{34} ]
= 5^{34}. (23 + 26 )
= 5^{34}. 49
