3.5^2x-1=5¹⁷.(13+62)                               

3.5^2x-1=5¹⁷.75                            

5^2x-1   =5¹⁷.75:3

5^2x-1  =5¹⁷.25

5^2x-1  =5¹⁷.5²

5^2x-1  =5¹⁹

2x-1  =19

2x     =19+1

2x     =20

x       =20 :2

x       = 10                   Vậy x = 10

3*5^2x-1=5^17(13+62)

               =?

Tìm đa thức N biết N chia x+2 dư 10, N chia x-2 dư 24, N chia \(x^2-4\)được thương là -5x và còn dư

\(M=\frac{2.2^{12}.3^6+2^2.2^9.3^9}{2^5.2^7.3^7+2^7.2^3.3^{10}}\)

\(=\frac{2^{11}.3^6\left(2^2+3^3\right)}{2^{10}.3^7\left(2^2+3^3\right)}\)

\(=\frac{2}{3}\)

\(M=\frac{2.\left(2^3\right)^4.\left(3^3\right)^2+2^2.\left(2.3\right)^9}{2^5.\left(2.3\right)^7+2^7.2^3.\left(3^2\right)^5}\)

\(M=\frac{2.2^{12}.3^6+2^2.2^9.3^9}{2^5.2^7.3^7+2^7.2^3.3^{10}}\)

\(M=\frac{2^{13}.3^6+2^{11}.3^9}{2^{12}.3^7+2^{10}.3^{10}}\)

\(M=\frac{2^{11}.3^6\left(2^2.1+1.3^3\right)}{2^{10}.3^7\left(2^2.1+1.3^3\right)}\)

\(M=\frac{2.31}{3.31}\)

\(M=\frac{2}{3}\)

Study well 

Đề bài mình nghĩ là đúng, còn về cách làm thì bạn theo công thức " số lớn nhất thỏa mãn trừ đi số nhỏ nhất thỏa mãn, rồi chia cho khoảng cách giữa các số rồi cộng 1"
