Simplify the expression and rationalize the demonimator when appropriate, please show steps : >

Step-by-step explanation:

So we have the expression:

To simplify, combine the two radicals. Since they have the same index, we can combine them. Thus:

Combine like terms:

Multiply. When multiplying the exponents, simply add the exponents:

Now, simplify. Note that -27 can be written as (-3)^3. t^3 can be written as (t)^3 and v^6 can be written as (v^2)^3. Thus:

Combine them all under one exponent:

Cancel out the cube root:

And this is the simplest it can get.

And we are done :)
