Question

tìm x

Answer 1

(1/2x-3)^3=27/64

=>(1/2x-3)^3=(3/4)^3

=>1/2x-3=3/4

=>1/2x=3/4+3=15/4

=>x=15/4:1/2=15/2

Answer 2

(1/2 x - 2)³ = 27/64

(1/2 x - 2)³ = (3/4)³

1/2 x - 2 = 3/4

1/2 x = 3/4 + 2

1/2 x = 11/4

x = 11/4 : 1/2

x = 11/2

Answer 3

\(\left(\dfrac{1}{2}x-2\right)^3=\left(\dfrac{3}{4}\right)^3\)

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

\(=>\dfrac{1}{2}x=\dfrac{11}{4}\)

\(=>x=\dfrac{11}{2}\)

Answer 4

\((\frac{1}{2}x-2)^3=\frac{27}{64}\)
\(\Rightarrow\) \((\frac{1}{2}x-2)^3=(\frac{3}{4})^3\)
\(\Rightarrow\) \(\frac{1}{2}x-2=\frac{3}{4}\)
\(\Rightarrow\) \(\frac{1}{2}x=\frac{11}{4}\)

\(\Rightarrow\) \(x=\frac{11}{2}\)
