GCF stands for greatest common factor so if u have a problem like let's say, "What is the gcf of 36 and 90?" all u do is go down your multiples table and write them all down till 36 you will get 9 and if u take 10×9 it equals 90. For LCM all you do is go down your multiples table and find the least number that is the same with each other.
True
When multiplying exponents with the same base you add the exponents
-1+3=2
I did this problem for homework. The picture below has both answers.
When finding the area of a rectangle, you do area=length*width
length= 3
width= 1/4
a= 1/4*3
a=3/4 square feet
It will have 2 solutions because, if you take out the (-) it will be a whole diffrent answer!
