#25#

Explanation:

Always count the number of terms first. That will tell you where to start. Each term must simplify to a single answer. The answers are added or subtracted in the last step.

#(5^3 + 25 -: -1) -: -4 " there is only 1 term"#

However within the brackets there are several terms, each needs to calculated separately.

#(color(red)(5^3)color(blue)( + 25 -: -1)) -: -4#

#(color(red)(125)color(blue)( -25)) -: -4#

#color(magenta)((100) -: -4)#

#25#
