Tính Nhanh:
a,64 x 7 +81 x 93 + 17 x 7
b,4 x 28 + 92 x 44 + 56 x 6 + 59 : 56
a, 64 x 7 + 81 x 93 + 17 x 7
= 7 x ( 64 + 17 ) + 81 x 93
= 7 x 81 + 81 x 93
= 81 x ( 93 + 7 )
= 81 x 100
= 8100

a) 64 x 7 + 81 x 93 + 17 x 7
= 7 x ( 64 + 17 ) + 81 x 93
= 7 x 81 + 81 x 93
= 81 x ( 7 + 93 )
= 81 x 100
= 8100

a) (x-1)* (x-3) *(x+5)*(x +7) - 297 = 0
b) x4 - 2x2 + 144x - 1295 = 0
c) \(\dfrac{1927-x}{91}+\dfrac{1925-x}{93}+\dfrac{1923-x}{95}+\dfrac{1921-x}{97}+4=0\)
d) \(\dfrac{x-85}{15}+\dfrac{x-74}{13}+\dfrac{x-67}{11}+\dfrac{x-64}{9}=10\)
a) Đặt x -3 = a
<=> a(a+2)(a+8)(a+10) - 297=0
<=> \(\left[a\left(a+10\right)\right]\left[\left(a+2\right)\left(a+8\right)\right]\)-297=0
<=> \(\left(a^2+10a\right)\left(a^2+10a+16\right)-297=0\)
Đặt \(a^2+10a=b\)
\(b^2+16b-297=0\)
\(\Rightarrow\left[{}\begin{matrix}b=11\\b=-27\end{matrix}\right.\)\(b=11\Rightarrow\left[{}\begin{matrix}a=1\\a=-11\end{matrix}\right.\) \(\Rightarrow\left[{}\begin{matrix}x=4\\x=-8\end{matrix}\right.\)
b= -27 \(\Rightarrow a=\varnothing\Rightarrow x=\varnothing\)
b) bấm máy ra nhân tử chung :D
c)
\(\Leftrightarrow\left(\frac{1927-X}{91}+1\right)+\left(\frac{1925-x}{93}+1\right)+...=0\)
\(\Leftrightarrow\frac{2018-x}{91}+\frac{2018-x}{93}+\frac{2018-x}{95}+\frac{2018-x}{97}=0\)
\(\Leftrightarrow\left(2018-x\right)\left(\frac{1}{91}+\frac{1}{93}+\frac{1}{95}+\frac{1}{97}\right)=0\)
<=> x = 2018
d) \(\Leftrightarrow\left(\frac{x-85}{15}-1\right)+\left(\frac{x-74}{13}-2\right)+\left(\frac{x-67}{11}-3\right)+\left(\frac{x-64}{9}-3\right)=0\)
