You are taking a muliple choice test that has 6 questions. Each of the questions has 4 answer choices with one correct answer per question. If you select one of these choices for each questions and leave nothing blank, in how many ways can you answer the question?

720

Step-by-step explanation:

becasue there are 6 questions, and 4 possible answes for each

there are 24 diffrent answers if u just choose everything once, like a a a a a a for each,  but then u have to do a a a a a b and a a a a a c etc.

so u do 6*5*4*3*2*1

permunatation

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
