a,A=2018^(1*9*4*6)*(9*4*7)***(1*9*9*9)
b,B=(1000—1^3)*(1000—2^3)*(1000—3^3)***(1000—50^3)
Tính a, (1000-1^3)×(1000-2^3)×..... ×(1000-50^3)
b,2008^[(1×9×4×6)×(1×9×4×7)×.....×(1×9×9×9)]
CHO MÌNH CÁCH LÀM NHA
Tính nhanh A = (1000-1^3).(1000-2^3).(1000-3^3).................(1000-50^3)
Tính hợp lý : A = (-1)2.(-1)3.(-1)4......(-1)100
B = ( 1000-13)(1000-23)(1000-33).....(1000-253)
C =(1/2 - 1)(1/3-1) (1/4-1)...(1/2006-1) (1/2007-1)
A=(1+1999/1).(1+1992/2).(1+1999/3)...(1+1999/1000)/(1+1000/1).(1+1000/2).(1+1000/3)...(1+1000/1999)
Tính A
Tính nhanh:
A=(1000-1^3).(1000-2^3)..........(1000-2010^3)
Tính nhanh:
a) (1000-1)3. (1000-2)3..........(1000-15)3
b) A= 2018(1000-1)^3 . (1000-2)^3..........(1000-100)^3
giups Mik vs nhé!!
