I think you can solve it by
=(x^2 - y^2) *( x^2 + y^2)
= (x -y)*(x+y)*(x^2 + y^2)
Answer:
729.
Step-by-step explanation:
For this you need to find the lcm of 36 and 60 = 180
therefore :
Mel needs to buy 5 packets of cups
(36*5=180cups)
and 3 packets of plates (60*3=180 plates)
Answer:
There are 36 possibilities per character (26 lower case letters + 10 numbers), so the total number of permutations are 36^4 = 1,679,616
