Question

Answer 1

`a, x - 1/3 = 4/25`

`x = 1/3 + 4/25`

`x = 37/75`

Answer 2

a: =>x-1/3=4/25

=>x=4/25+1/3=12/75+25/75=37/75

b: =>(x+2)⁶=2⁶

=>x+2=2 hoặc x+2=-2

=>x=0 hoặc x=-4

d:\(\Leftrightarrow\left(\dfrac{x+10}{22}-1\right)+\left(\dfrac{x+8}{20}-1\right)+\left(\dfrac{x+6}{18}-1\right)=0\)

=>x-12=0

hay x=12
