answer quick please? simplify the expression

Answer:
1/3
Step-by-step explanation:
So because of BODMAS / PEDMAS / whatever you call it, you do the brackets first.
(7-2) = 5
5 squared is 25
So 25 is on the top.
Then we do the bottom one. We do square/cubed/quadrupled numbers first, so 3 to the power of 4 is 81.
4+81=85
85-10=75
So the bottom number is 75.
25 / 75 is the fractions so simplified that would be 1/3
