Answer:

\frac{3375}{512} or ≈6.59

Step-by-step explanation:

We can first begin by simplifying each of the numbers with exponents. Recall that in a fraction exponent, the numerator is the power, while the denominator is the root.

Take 25\frac{3}{2} for example. The '2' in the fraction means we must take the square of 25. √25 = 5.

The '3' in the fraction means we take the power, which means we must cube '5'.

5³ = 125. Therefore, 25\frac{3}{2}  = 125. Use this process for the other numbers:

25^{\frac{3}{2} } = 125\\243^{\frac{3}{5} } = 27\\16^{\frac{5}{4} } = 32\\ 8^{\frac{4}{3} } = 16

The new fraction would look like:

\frac{125 * 27}{32 * 16}

Which simplifies to:

\frac{3375}{512} or ≈6.59
