First, let's find all the factors of 81:
81/3=27
27/3=9
9/3=3
3/1=1
So the factors of 81 are 3,3,3,3, (the numbers by which we divided here).
This means we can write down 81 as 3*3*3*3 or
- which is the answer to the question! (three to the power of 4)

Answer:
Step-by-step explanation:
Evaluating the numerator and denominator before evaluating
Using the rule of exponents
⇔
,
= 1
Thus
y² ← substitute values into expression
= × 4² =
× 16 =
and denominator
= 1 × 4³ = 1 × 64 = 64
Now dividing
÷ 64
= ×
( cancel 16 and 64 )
= =
