Shauntale,

Following the order of operations in mathematical expressions ((1) Parenthesis, (2) Exponents, (3) Multiplication, (4) Division, (5) Addition and (6) Subtraction) the expression is simplified as follows: 5+9^3 = 5 + 729 = 734.

The exponential operation is done first in the expression given above (9^3=9*9*9=729). Then the addition is done. Therefore 5 is added to 729 to get a final answer of 729.

I hope this helps!

In order to solve this problem you must follow the Order of Operation Rules. In this case the 9^3 operation is done first. The answer is then added to 5.  So 9^3 = 9 x 9 x 9 = 729.   Then, 5 + 729 = 734.

5+9^3 = 734.

If the problem was written as (5+9)^3, then you would add 5 + 9 = 14 and then 14^3

14 x 14 x 14 = 2744.

In general the Order of Operation is  from first to last:

Raising to exponents
Multiplying/Dividing

Always perform operation inside parenthesis ( ) before applying operations outside the parenthesis.

Hope that help,
