Remove all extra parenthesis from the expression.
7((24)/(8)*2+(2^(4)-2^(3)))
Reduce the expression (24)/(8) by removing a factor of 8 from the numerator and denominator.
7(3*2+(2^(4)-2^(3)))
Raising a number to the 4th power is the same as multiplying the number by itself 4 times. In this case, 2 raised to the 4th power is 16.
7(3*2+(16-2^(3)))
Cubing a number is the same as multiplying the number by itself 3 times (2*2*2). In this case, 2 cubed is 8.
7(3*2+(16-8))
Subtract 8 from 16 to get 8.
7(3*2+(8))
Remove the parenthesis around the expression 8.
7(3*2+8)
Multiply 3 by 2 to get 6.
7(6+8)
Add 8 to 6 to get 14.
7(14)
Complete the multiplication of 7 by each term inside the parenthesis.
Your answer is 98
