(169-42):(169-52...169-132) = ?
Tính
E=(169-4^2).(169-5^2).(169-6^2).(169-7^2).(169-8^2).(169-9^20).(169-10^2).(169-11^2).(169-12^2).(169-13^2)
(169-4^2)(169-5^2).....(169-13^2)
Tính : (169 - 4^2) . (169 - 5^2) ... (169 - 13^2)
(169-42).(169-52)…(169-122).(169-132)
=(169-42).(169-52)…(169-122).(169-169)
=(169-42).(169-52)…(169-122).0
=0
(169 - 4^2) . (169 - 5^2) ... (169 - 13^2)
=(169-4^2).(169-5^2)...(169-169)
=0
(169 - 4 mũ 2) (169 -5 mũ 2) ...( 169 - 13 mũ 2)
(169 - 4 mũ 2) (169 -5 mũ 2) ...( 169 - 13 mũ 2)
= (169-42)(169-52)...(169-132)
=(199-42)(169-52)...(169-169)
=_____________...0
= 0
giải giúp mình bài toán sáu nha /: (169-4^2).(169-5^2).....(169-13^2)=?
tinh nhanh dau cham la nhan
(169-4^2).(169-5^2).....(169-13^2)
=(169-4^2).(169-5^20).....(169-169)
= 169-4^2).(169-5^20).......0
= 0
