The value of this expression is:

(27x^6)/6427x664

Explanation:

(16/(9x^4))^(-3/2)=((9x^4)/16)^(3/2)=((3x^2)/4)^3=(27x^6)/64(169x4)32=(9x416)32=(3x24)3=27x664

In the first step I used the rule that:

a^-b=1/a^bab=1ab

The second step is :

a^(1/n)=root(n)(a)a1n=na

Final step is just calculating the cube (third power) of the expression

color(red)((27x^6)/6427x664

Explanation:

(16/(9x^4))^-(3/2)(169x4)(32)

:.=(4^2/(3^2x^4))^-(3/2)

:.=(4^(2 xx -3/2))/(3^(2 xx -3/2)x^(4 xx -3/2)

:.=(4^(-6/2))/(3^(-6/2)x^(-12/2))

:.=(4^-3)/(3^-3 x^-6)

:.=(1/4^3)/(1/3^3*1/x^6)

:.=1/4^3 xx 3^3/1 xx x^6/1

:.=color(red)((27x^6)/64
