Step 1 : Rewrite the problem ...
(3^8 x 2^ -5 x 9^0)^ -2 x (2^-2/3^3)^4 x 3^28
Any non-zero expression raised to the power of equals
Step 2:(3^8 x 2^-5 x 1)^-2 x (2^-2/ 3^3)^4 x 3^28
Step 3: (3^8 x 2^-5 x1)^-2 x 2^-8/ 3^12 x 3^28
Any expression multiplied by remains the same
Step 4 : (3^8 x 2^-5)^-2 x 2^-8/3^12 x 3^28
To raise a product to a power, raise each factor to that power
Step 5 : 3^-16 x 2^10 x 2^-8/ 3^12 x 3^28
Reduce the expression with
Step 6: 3^-16 x 2^10 x 2^-8 x 3^16
Calculate the product
2^2
Evaluate , and then your answer is 4!!!!
