Creative Thinking

The necklace follows a pattern where one set is 2 green beads and 3
purple beads. The following shows the continuation of the pattern on the
necklace.

4 green beads and 7 purple beads are needed.
The numbers in the 4 squares increase by 1 and rotate clockwise.

45
55

The numbers can be grouped in 3s: (1, 1, 8) (2, 2, 6) (3, 3, ). The sum of
the numbers in each group is 1+1+8=2+2+6=10, so 3+3+ =10.

=4.
The product of the numbers in the top and bottom circles is: 2^1=2,
1^3=3, 4^2=8, and 3^3=9. When the product of the two numbers in
the circles is added to the number in the triangle, the result is always 10.
2^1+8=10, 1^3+7=10, 4^2+2=10, 3^3+1=10. So, in the 5th
figure, if is the missing number, ^5+5=10, so =1.

Find A, B, and C by following the rules of a multiplication table.
A: 2^8=16
B: 7^9=63
C: 9^4=36
In the multiplication table, 24 shows up for both 4^6 and 6^4. The
only time 28 falls below 24 on the multiplication table is when the 24 is
the result of 6^4.
