Ta có : \(x=99\Rightarrow x+1=100\)
\(\Leftrightarrow P\left(99\right)=x^{99}-\left(x+1\right)x^{98}+\left(x+1\right)x^{97}-...+\left(x+1\right)x-1\)
\(\Leftrightarrow x^{99}+x^{98}+x^{97}+...+x^2+x-1\)
\(\Leftrightarrow x-1\) Thay x = 99 vào x - 1 ta có
\(\Leftrightarrow P\left(99\right)=99-1=98\)
Cho Q(x) =x99 -100x98+100x97-100x96+...+100x-1.tính Q(99)
1.
Cho P(x)=100x100+99x99+98x98+...+2x2+x
Tính P(1)
2.
P(x)=x99-100x98+100x97+100x96+...+100x-1
Tính P(99)
Cho P(x) = x^99-100x^98 +100x^97-100x^96+...+100x-1
Tính P(99)
Tính giá trị đa thức:B=\(x^{99}-100.x^{98}+100.x^{97}-100.x^{96}+...+100.99-1\)tại x=99
: Cho P(x) = x99 – 100x98 +100x97 – 100x96 +… +100x – 1
Tính P(99) Đ/S: P(99) = 98
Tính B biết x=99\(B=x^{99}-100.x^{98}+100.x^{97}-100.x^{96}+...+100.99-1\)
Cho P(x)= x99 - 100x98 + 100x97 - 100x96 +.......+ 100x - 1
Tính P(99)=???
Giúp mình nha:
Cho P(x)=x99-100x98+100x97-100x96+100x-1
Tính P(99)
Cho \(P\left(x\right)=x^{99}-100x^{98}+100x^{97}-100x^{96}+...+100x-1\)
Tính P(x)
