The correct answer is
125

Simplifying the Exponential Expression $(25)^{\frac{3}{2}}$

To simplify the expression $(25)^{\frac{3}{2}}$, we can use the properties of exponents.

Exponent Rule Application

Recall the exponent rule: $(a^m)^n = a^{m \times n}$. We can rewrite 25 as $5^2$. Substituting this into the expression gives:

$ (25)^{\frac{3}{2}} = (5^2)^{\frac{3}{2}} $

Now, apply the rule $(a^m)^n = a^{m \times n}$:

$ (5^2)^{\frac{3}{2}} = 5^{(2 \times \frac{3}{2})} = 5^3 $

Calculating the Final Value

Finally, calculate $5^3$:

$ 5^3 = 5 \times 5 \times 5 = 125 $

Therefore, the simplified value of $(25)^{\frac{3}{2}}$ is 125.
