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

My answer: 109

4) [25/ (2^3-3)]*2

My way of solving:

[25/(8-3)]*2

[25/5]*2

[5]*2

My answer:10

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.**
My answer:10
