Answer:

#29#

Explanation:

Always count the number of terms first. EAch term will give a final answer and these are added or subtracted (left to right) in the final step.

The expression has 3 terms, but there are 2 separate terms inside the bracket.

#25-(2+color(red)((4-2))^2)+10#

=#25 - (2+color(blue)((2)^2))+10#

=#25 -color(lime)((2+4))+10#

=#color(magenta)(25)-6color(magenta)(+10)" "larr# 3 terms: calculate from left to right

OR

=#color(magenta)(25+10)-6" "larr# re-arrange with + at the front

=#29#
