Someone please help me :( ?

Answer:
[tex]\frac{1}{6^{3} }[/tex]=[tex]\frac{1}{216}[/tex]
Step-by-step explanation:
The expression given follows the Laws of Exponents. In the Laws of Exponents, a base can not have a negative exponent. In this case, the number '6' is the base and '-3' is the exponent. When you have a base with a negative exponent you form the reciprocal of the base and make the exponent positive:
Reciprocal of '6' = [tex]\frac{1}{6}[/tex] and the exponent '-3' becomes '+3' for a final answer of:
[tex]\frac{1}{6^{3} }[/tex]=[tex]\frac{1}{216}[/tex]
