Toán (x-2/15)^3=8/125 Giải hộ mình vote 5 sao luôn ạ 06/07/2021 By Quinn (x-2/15)^3=8/125 Giải hộ mình vote 5 sao luôn ạ
$( x – \dfrac{2}{15} )^{3} = \dfrac{8}{125}$ $⇔ (x – \dfrac{2}{15})^{3} = (\dfrac{2}{5})^{3}$ $⇔ x – \dfrac{2}{15} = \dfrac{2}{5}$ $⇔ x = \dfrac{2}{5} + \dfrac{2}{15}$ $⇔ x = \dfrac{8}{15}$ Trả lời
$( x – \dfrac{2}{15} )^{3} = \dfrac{8}{125}$
$⇔ (x – \dfrac{2}{15})^{3} = (\dfrac{2}{5})^{3}$
$⇔ x – \dfrac{2}{15} = \dfrac{2}{5}$
$⇔ x = \dfrac{2}{5} + \dfrac{2}{15}$
$⇔ x = \dfrac{8}{15}$
(x-2/15)³=8/125
(x-2/15)³=2/5³
x-2/15=2/5
x=2/5+2/15
x=8/15
Vote mình 5 sao heng :v
