Last one for today! Again would appreciate a breakdown on how to get to a resolution. It is multiple choice. 1. Simplify the expression using the quotient to a power property. (3y^6/z^7)^3 a. 27y^9/z^7 b. 3y^9/z^10 c. 27y^18/z^7 d. 27y^18/z^21 2. Use a descriptive variable and...
I have a few more questions that I'm not understanding. Its multiple choice however I would appreciate a breakdown on how to solve. 4.Simplify the compound rational expression. Use either method. 1+(5/y-10)/y+(25/y-10) a. 1/y-5 b. 1/y+5 c. 6/y+25 d. 1/y+1/5 5.Simplify the ...
I have a few more questions that I'm not understanding. Its multiple choice however I would appreciate a breakdown on how to solve. 1.Evaluate without a calculator, using the order of operations. -2^2+20-|8-20|-squareroot of 64 a. -36 b. 4 c. 28 d. -4 2.Simplify the expres...

Hi, For my physics class, we have to design our own experiments to calculate the amount of power exerted for each situation. However, I'm really unsure of how to go about finding the power for the situations. The first situation is doing a push-up, and the second is pushin...
