If you can answer this question please do it as soon as you can.

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

Cthe residual plot for model 1 has a non random pattern and is a good fit for the data
