2. simplify the rational exponent expression as a radical expression. (729x^3y^-18)^1/6
*answer choices in linked pics*

1) Option A) is correct

The given rational exponent expression is not simplified correctly as a radical expression is

2)Option A) is correct

That is

Step-by-step explanation:

1) Given that

is the correct answer but in the given problem they gave the RHS as wrong.

Therefore the given rational exponent expression is not simplified correctly as a radical expression is

2)Given that the rational exponent expression is

To find it as a radical expression:

Therefore

Therefore Option A) is correct

That is

right

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
