Fill in the banks to simplify the expression

Answer:
4^3/8+3([ 4 ])-5^2
[ 64 ]/8+3([ 4 ])-5^2
[ 64 ]/8+3([ 4 ])-[ 25 ]
[ 64 ]/8+[ 12 ]-[ 25 ]
[ 8 ]+[ 12 ]-[ 25 ]
[ 20 ]-[ 25 ]
[ -5 ]
Answer:
The final answer is -5.
Step-by-step explanation:
4^3 / 8 + 3 (7-3) - 5^2
4^3 / 8 + 3( 4 ) - 5^2
64 / 8 + 3( 4 ) - 25
64 / 8 + 12 - 25
8 + 12 -25
20 - 25
= -5
So the first part you subtract the numbers in brackets.
Then you reduce the powers as in simplifying them.
From there you multiply 3 and 4.
Then you divide 64 and 8
After that you do the rest just as they are.
