Sorry bro I’m in algebra 1 not calculus but good luck bro ✊
Answer:
1/3 is the simplified form for given expression.
Step-by-step explanation:
Given that:
=
By simplifying:
Radical sign will be removed as follows:
=
For removing the "-" sign from power, base will be inverted:
=
27 can also be written as 3 * 3 * 3 = 3^3
So,
=
=
By simplifying we get:
= 1/3
