(5)353=1

Explanation:

(5)353

The issue here is dealing with the negatives. We should note that the minus sign in the numerator is contained within the power of 3, whereas there is a single, standalone minus 1 in the denominator which is multiplied by 53. Rewriting to clarify, then, we have:

=[1(5)]31(53)

Distributing the power:

=(1)3531(53)

Note that (1)3=(1)(1)(1)=1:

=153153

=1
