Simplify the expression.

4 (3^ (3) - 8) : 2

First thing we are going to do is solve the problems in the parenthesis, so 3 to power of 3 is 27 (3 * 3 * 3) then minus 8 should be 19.

Second thing we are going to do is multiply 4 by 19 which is 76.

FInally divide by 2.

The answer is 38.

4 (27-8) divided by 2

4 times 19 divided by 2

76 divided by 2

38
