Answer:

For the expression you've given, (3/5)^(-3) ÷ (5/3)^5, first simplify the exponents and then calculate the reciprocal.

Explanation:

Here's the step-by-step process:

(3/5)^(-3) = (5/3)^3 (taking reciprocal of both sides)

(5/3)^5 = 5^5 / 3^5

Now the expression becomes:

(5/3)^3 ÷ (5^5 / 3^5)

Next, simplify the division by multiplying with the reciprocal of the second term:

(5/3)^3 * (3^5 / 5^5)

Now calculate the values:

(125/27) * (243 / 3125)

Multiply the numerators and denominators separately:

(125 * 243) / (27 * 3125)

Finally, calculate the result:

(30375) / (84375)

Now, to find the multiplicative inverse, take the reciprocal of the result:

1 / (30375 / 84375)

Which simplifies to:

84375 / 30375

So, the multiplicative inverse of the given expression is 28125/10125, which can be simplified to 75/27
