anonymous · Answer

well those with the sum of powers being high are written first

anonymous · Answer

so lol what does that mean? i'm so confused

anonymous · Answer

a3b 

what is the sum of powers here?

anonymous · Answer

3?

anonymous · Answer

no

a3b = a3b1

sum of powers = 3+1 = 4

anonymous · Answer

oh my okay...so is that how to solve the problem?

anonymous · Answer

yea find it for the rest to

and arrange them in decreasiong order of their 'sum of powers'

anonymous · Answer

could you walk me through the first one ?
please

anonymous · Answer

3a3b – 4ab2 + a2

a3b = 3+1 = 4

ab2 = 1+2 = 3

a2 = 2

already in decreasing order  4,3,2

so this is standard form

anonymous · Answer

ohhhhhhhhhhhh okay! lol thanks

anonymous · Answer

hahaa u r welcome

anonymous · Answer

u may close the question now lol

anonymous · Answer

2. –8x2y2 + 10xy4 – 6x2y
x2y2= 2+2=4
xy4=4+1=5
xy2=1+2=3
Not in decending order 



is this correct?

anonymous · Answer

awsumm, yepp

anonymous · Answer

alrightyy thanks again :)

anonymous · Answer

welcome again lol :D
