4 + 3(10 - 2^3)
A)8
B)10
C)11****
D)12
make sure you follow the order of operations
4 + 3(10 - 2^3)
= 4 + 3(10 - 8)
= 4 + 3(2)
= 4 + 6
= 10
how did you get 11 ??
lets just say exponents hate me.....a lot....and that somehow my calc said 9 and not 8 so thank you greatly.......
You probably did 3^2 instead of 2^3
--- neither one of which requires a calculator
Thanks
BTW I have a sis waiting to play so a calc is the fastest way to go right now
To solve this mathematical expression, follow the order of operations (PEMDAS/BODMAS).
Step 1: Simplify within parentheses or brackets.
In this case, we have 2^3 which equals 8. So the expression becomes:
4 + 3(10 - 8)
Step 2: Perform the subtraction.
10 - 8 = 2
The expression now becomes:
4 + 3(2)
Step 3: Multiply.
3 multiplied by 2 equals 6.
The expression now becomes:
4 + 6
Step 4: Add.
4 + 6 = 10
Therefore, the correct answer is B) 10.
