STEP 1

What is this asking? We're asked to simplify an expression with exponents and make sure all the exponents are positive! Watch out! Don't forget the rules of exponents!
A negative exponent means "reciprocal," not "negative number." Also, anything (except 0) raised to the power of 0 is 1!

STEP 2

1. Handle the negative exponent
2. Handle the zero exponent
3. Combine and simplify

STEP 3

Alright, let's **rewrite** that 424^{-2}.
Remember, a negative exponent means "take the reciprocal," so 424^{-2} becomes 142\frac{1}{4^{2}}.
It's like flipping it!
So our expression is now 1428056\frac{1}{4^{2}} \cdot 8^{0} \cdot 5^{6}.

STEP 4

Now, let's look at 808^0.
Anything (except 0) raised to the power of zero is **1**!
So, 80=18^0 = 1.
Our expression becomes 142156\frac{1}{4^{2}} \cdot 1 \cdot 5^{6}.
Multiplying by 1 doesn't change anything, so we can simplify to 14256\frac{1}{4^{2}} \cdot 5^{6}.

STEP 5

Let's put it all together!
We have 14256\frac{1}{4^{2}} \cdot 5^{6}, which is the same as 5642\frac{5^{6}}{4^{2}}.
That's it!
All exponents are positive, and we've simplified the expression.

STEP 6

Our **final simplified expression** is 5642\frac{5^{6}}{4^{2}}.
