Simplifying algebraic expression and Simplifying exponential expression?

Question

hello there (: i just need some help, it would be wonderful if you also added the detailed work process along with the accurate answer. once you've allowed me to read your shared answer, i will try to learn and understand the process therefore i can apply it to the rest of the work i have for today, thank you *

ill do one cus i dont want you to fail ur test 

first u do order of opporations PEMDAS  

after that do the multiply 2 byt the answer u got in parenthesese on the right  then subtract that but the one on the left

1. first use the distributive property to get    4*5y - 4*3 -2*6y +(-2)*3
 then do multiplications to get     20y - 12 -12y - 6
then add like terms to get    8y -18

2. if you have the same base number, in your question it is a 5, then you subtract the exponent in the denominator from the one in the numerator
so the question becomes 5^(3-5) which simplifies to 5^-2 which could also be written as 1/5^2
or 1/25
