I think 81 is composite and is 9 squared. 81 = 1 x 81, 3 x 27, or 9 x 9. Factors of 81: 1, 3, 9, 27, 81. Prime factorization: 81 = 3 x 3 x 3 x 3 which can also be written 3⁴. Since √81 = 9, a whole number, 81 is a perfect square. Even though it has other factors, the only multiplication fact we use is 9 x 9 = 81.
Step-by-step explanation:
Since each cookie has 9 grams of fat, four cookies would contain 4*9 = 36 grams of fat.
Also nine cookies has 7*9 = 63 grams of fat.
So the number of grams consumed will be at least 36 and no more than 63.
Answer:
There are 52 such numbers that have even divisors.
Step-by-step explanation:
All the numbers between 2 and 59 have an EVEN number of positive divisors.
Except the Perfect Squares..
or 4, 9, 16, 25, 36 and 49, which have 3 divisors each.
So:
59 - 2 + 1 =58
Now subtract 58 from 6 (perfect squares)
58- 6=52
Therefore,it means that there are 52 such numbers that have EVEN divisors....
