ai giúp mik y

 

Answer 1

Sửa: \(\left(\dfrac{3}{4}-x\right)^3=\dfrac{1}{64}=\left(\dfrac{1}{4}\right)^3\)

\(\Rightarrow\dfrac{3}{4}-x=\dfrac{1}{4}\\ \Rightarrow x=\dfrac{3}{4}-\dfrac{1}{4}=\dfrac{1}{2}\)

Answer 2

⇒34−x=14⇒x=34−14=12

Answer 3

3/4 - x =1/64

        x =3/4-1/64

        x =48/64 - 1/64

        x =47/64

Vậy x= 47/64
