The expression shown in the image is:

$\left(\frac{m^3}{n^2}\right)^4$

To simplify this expression, we need to apply the power rule, which states that when raising a fraction to an exponent, both the numerator and denominator are raised to that exponent. This leads to:

$\frac{(m^3)^4}{(n^2)^4}$

Now apply the exponent to both terms:

$m^{3 \times 4} = m^{12}, \quad n^{2 \times 4} = n^8$

So, the simplified expression is:

$\frac{m^{12}}{n^8}$
