tìm x biết a)\(\frac{x-100}{24}+\frac{x-98}{26}+\frac{x-96}{28}=3\)
b)\(\frac{x-28-124}{2011}+\frac{x-124-2011}{28}+\frac{x-2011-28}{124}=3\)
Tính :
\(A=-66.\left(\frac{1}{2}-\frac{1}{3}+\frac{1}{11}\right)+124.\left(-37\right)+63.\left(-124\right)\)
bài 1: Cho A ( x ) = x99 - 100x98 + 100x97 - 100x96 +...+ 100x-1 . Tính A ( 99 )
bài 2: Cho P(x) = 100x100 + 99x99 +...+ 2x2 + x . TÍnh P(1)
Tìm x,y
2x + 124 =5y
Tìm x, y, z, biết:
\(\frac{x}{3}=\frac{y}{2};\frac{x}{5}=\frac{z}{7}\) và x+y+z=184
tìm x
2^x+2 - 2^x = 96
Tìm x biết:
a) 7x+2 + 2.7x-1= 345
b) 2x+2 - 2x= 96
Cho a(x) = x99 - 100x98 + 100x97 - 100x96 + ...+ 100x-1
Tính a(99)
