16x^4=1048576

解

16 x^{4} = 1048576

解

x = 16, x = - 16, x = 16 i, x = - 16 i

解答ステップ

16 x^{4} = 1048576

以下で両辺を割る

16

x^{4} = 65536

equationを

u = x^{2}

と以下で書き換える:

u^{2} = x^{4}

u^{2} = 65536

解く

u^{2} = 65536 : u = 65536, u = - 65536

u = 65536, u = - 65536

再び

u = x^{2}

に置き換えて以下を解く:

x

解く

x^{2} = 65536 : x = 16, x = - 16

解く

x^{2} = - 65536 : x = 16 i, x = - 16 i

解答は

x = 16, x = - 16, x = 16 i, x = - 16 i

-(a+1)^2(a-8)=0

- (a + 1)^{2} (a - 8) = 0

x^{2} + 6 x + 9 = 4 x^{4}

1400=700(1+x/(100))^5

1400 = 700 (1 + \frac{x}{100})^{5}

(xx^8)/5 =(-2)/(25)

\frac{x x ^{8}}{5} = \frac{- 2}{25}

x^{5} + 3 x^{3} - 10 x = 0
