6x^-3/2=162
6*x^1/3/ 2 = 162
X^6/3/2= 169
Cross multiply
6= 162x^3/2
Divide both side be 162
6/162= x^3/2
1/27= x^3/2
3/2√1/27 = x
(1/27)2/3 =x
1/(3^3)2/3 =x
1/3^3*2/3 =x
1/3^6/3=x
1/3²=x
1/9 =x
X= 1/9

Divide both side by 6
x^-(3/2)=27
Square both side.
x-³=729
Take the cube root of both side
x-¹=9
Take the inverse
x=1/9
