Question

rewrite the expression $12^{0} \cdot 5^{-2}$ using only positive exponents.
how can you rewrite $12^{0}$?
$12^{0} \cdot 5^{-2} = \square \cdot 5^{-2}$

Explanation:

Step1: Apply zero exponent rule

Any non-zero number to the power of 0 is 1.
$12^0 = 1$

Step2: Substitute back into expression

Replace $12^0$ with its simplified value.
$12^0 \cdot 5^{-2} = 1 \cdot 5^{-2}$
