Multiplication in GF(2^4): Compute multiplication A(x)*B(x) mod P(x) in GF(2^4) using the irreducible polynomial P(x) = x^4 +x+1 (show all the steps for both examples). What is the influence of the choice of the reduction polynomial on the computation of multiplication?

step-by-step explanation:

if the four friends split the cost, p, of the pizza evenly, then each friend pays one-fourth of the cost of the pizza.

the expression is   or  

ummm seems that u didnt post the attachement !

answer:   expression= p+p*d%

price reduction + sale price = $625

sale price: $p+$p*d%

where d% is the percentage of discount

step-by-step explanation:

original price = p

price went down by $150 price reduction $p*d%

sale price= $ 475

therefore the price before sale is: $625

and the expression that shows the price before sale is: p+p*d%
