Answer:
The symbol a^50 represents the result of raising the letter a to the power of 50. In other words, it means "a multiplied by itself 50 times".
Think of it like this:
a x a = a^2
a x a x a = a^3
a x a x a x a = a^4
And so on...
a x a x a x a x a = a^50
So, a^50 means "a multiplied by itself 50 times".
