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 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,  = 125. Use this process for the other numbers:

The new fraction would look like:

Which simplifies to:

or ≈6.59

Step-by-step explanation:

(25) raise to 3/2 = (5^2) raise to 3/2 and 2 gets cancelled when the bracket is opened which leaves 5^3.

(243) raise to 3/5 = (3^5) raise to 3/5 and 5 gets cancelled when the brackets are opened which leaves 3^3.

(16) raise to 5/4 = (2^4) raise to 5/4 and 4 gets cancelled when the bracket is opened which leaves 2^5.

(8) raise to 4/3 = (2^3) raise to 4/3 and 3 gets cancelled when the brackets are opened which leaves 2^4.

5^3 * 3^3 divided by 2^5 * 2^4

= (5 x 3)^ 3 / 2^5+4                   [∵a^m x b^m = (ab)^m] & [a^m x a^n = a^m+n]

15^3 / 2^9

This when simplified gives 6.591.

So,  15^3 / 2^9 is approximately equal to 6.59
