Find K such that:
Find K such that: K-2006=1+(1+2+3)+ ...(1+...+2007) / 2017*1+2016*2+2015*3+...+2*2016+1*2017
x³+y³+z³=8?
x³+y³+z³=42?
Find x, y, and z such that x³+y³+z³=k, for each k from 1 to 100.
A=3.4.10-8 and B=34.10-9. find the interger number k such that A=k.B
A=3.4.\(\frac{1}{10^8}\)=\(\frac{12}{10^8}\)
B=34.\(\frac{1}{10^9}\)=\(\frac{34}{10^9}\)
Ta có: A=k.B\(\Rightarrow\)\(\frac{12}{10^8}=k.\frac{34}{10^9}\)=>k=\(\frac{12}{10^8}:\frac{34}{10^9}\)=\(\frac{12}{10^8}.\frac{10^9}{34}\)=\(\frac{60}{17}\)
Find the value of k such that x3 + kx2 + (4 - k)x - 35 is divisible by x - 7.
Answer: k = ........
Dịch: Tìm giá trị của k nếu :\(x^3+kx^2+\left(4-k\right)x-35⋮\left(x-7\right)\)
=>x-7=0=>x=7 => Là nghiệm của phương trình .
Thế x=7 vào biểu thức , ta có :
\(7^3+k.7^2+\left(4-k\right).7-35\)
=\(343+49k+28-7k-35=>42k=-336=>k=-8\)
Vậy k=-8

Find x+y such that 2^x+80=3^y . Answer:
anh làm nhanh nhất mình sẽ k
chỉ cần đáp án thôi !!!!!
2^x + 80 = 3^y
ta có 3^y là lẻ nên 2^x + 80 là lẻ . với x = 1 thì 2^x + 80 là chẵn không thỏa mãn nên x = 0
1 + 80 = 36y
81 = 3^y
3^4 = 3^y => y = 4
Find K such that:
K - 2016 = \(\frac{1+\left(1+2\right)+\left(1+2+3\right)+...+\left(1+2+3+...+2017\right)}{2017\times1+2016\times2+2015\times3+...+2\times2016+1\times2017}\)
Tử số bằng mẫu số
K-2016=1
K=2017
Muốn biết tại sao tử= mẫu thì tích nha
\(K-2016=\frac{1+\left(1+2\right)+\left(1+2+3\right)+...+\left(1+2+3+...+2017\right)}{2017\times1+2016\times2+2015\times3+...+2\times2016+1\times2017}\)
\(K-2016=\frac{1\times2017+2\times2016+3\times2015+...+2017\times1}{2017\times1+2016\times2+2015\times3+...+2017\times1}\)
\(K-2016=1\)
\(\Rightarrow K=1+2016\)
\(\Rightarrow K=2017\)
Find M such that m*(m+2)=168
dịch:
Tìm M nếu m*(m+2)=168
Ta có:
m(m+2)=168
Mà 168=12.14 nên m=12
Tick nha !
Given that a*b=(a+b):2.Find x such that x*(x+4)=7
