Answer:
Value of
is, 1
Step-by-step explanation:
To find the value of ![[(\frac{2}{3})^0]^{-3}](https://tex.z-dn.net/?f=%5B%28%5Cfrac%7B2%7D%7B3%7D%29%5E0%5D%5E%7B-3%7D)
Using exponents power rule:

then;

Simplify:

By Zero exponent rule: Anything raised to the power 0 is 1. i.e,

then;
= 1
Therefore, the value of
is, 1
To multiply exponents with like bases, simply add the exponents...
3^-3 × 3^4 × 3 × 3^-5 =
add exponents across, remember just 3 means 3^1.
-3 + 4 + 1 + -5 = -3
answer is 3^-3
