n^2+5log_{10}(n)=o(n^2)

解答

n^{2} + 5 lo g_{10} (n) = o (n^{2})

o = \frac{n ^{2} + 5 lo g _{10} ( n )}{n ^{2}}; n \neq = 0

求解步骤

n^{2} + 5 lo g_{10} (n) = o (n^{2})

交换两边

o (n^{2}) = n^{2} + 5 lo g_{10} (n)

两边除以

n^{2}; n \neq = 0

o = \frac{n ^{2} + 5 lo g _{10} ( n )}{n ^{2}}; n \neq = 0

so l v e f or m, d = n + 7 m

x - 9 = \frac{2}{3} (x + 1)

7 = \frac{2 c}{5} + 3

15 x = 12 (x - 3)

so l v e f or x, 3 y - 9 x = - 6
