Simplify the Expression $\frac { \left( x ^ { 7 } y ^ { 8 } \right) ^ { 5 } \left( x ^ { 2 } y ^ { 6 } \right) ^ { - 5 } } { x ^ { 2 } y ^ { 18 } }$

question 47

Short Answer

Simplify the expression. Eliminate any negative exponents. $\frac { \left( x ^ { 7 } y ^ { 8 } \right) ^ { 5 } \left( x ^ { 2 } y ^ { 6 } \right) ^ { - 5 } } { x ^ { 2 } y ^ { 18 } }$

Acetylcholine

A neurotransmitter involved in both the peripheral and central nervous systems, playing a critical role in muscle contraction and potentially in memory formation.

Excitatory
