Question:

Solve for 10^(2*4/8+(2-4+1))

Alec J.

Answer:

The answer is 1. Using the order of operations PEMDAS which stands for "Parentheses, Exponent, Multiplication, Division, Addition, Subtraction", we start by solving the inner parentheses: (2-4+1) = -1. Even though Addition comes before subtraction in the "word" PEMDAS we do whichever comes first between addition and subtraction. This is also true with multiplication and division. Once we have -1 in the inner parentheses, we then solve the outer set of parentheses. Remember, in the outer parentheses we have 2*4/8 + (-1). Now, according to PEMDAS we do multiplication or division and then the addition. We see that 2*4 = 8 THEN 8/8 = 1. So we have 10^(1 + (-1)) once again we add together all our remaining numbers in parentheses to get 0. The final step is to do 10^0, the exponent. A basic math rule is that any number to the power 0 is 1 thus 10^0 is 1. Here it is again step by step: 10^(2*4/8 + (2-4+1)) 10^(2*4/8 + (-1)) After Solving the inner parentheses 10^(8/8 + (-1)) After Solving 2*4 10^(1 + (-1)) AfterSolving 8/8 10^(0) After Solving 1 + (-1)) 1 = 10^0
