Can someone correct it

Evaluate the following expressions numbers 3-4

3) [(2+3)^3-4(5)]+7
My way of solving:
[(5)^3-4(5)]+7
[123-4(5)]+7
[123-20]+7
[103]+7

4) [25/ (2^3-3)]*2
My way of solving:
[25/(8-3)]*2
[25/5]*2
[5]*2

Thanks for showing your work. It helps us to know where you are having trouble.
#3. [(2+3)^3-4(5)]+7
My way of solving:
[(5)^3-4(5)]+7 You are ok to here.
[123-4(5)]+7 5*3 125 not 123.
[123-20]+7
[103]+7 a second mistake here. 103 + 7 = 110
My answer: 109 the correct answer is 112.

#4. [25/ (2^3-3)]*2
My way of solving:
[25/(8-3)]*2
[25/5]*2
[5]*2 You are ok to here. 5^2 = 25 and not 10.
