Since 8 is 2 x 4, 9 x 8 is 2 x 9 x 4
2 x 2 x 2 = 8 3 x 3 = 9 2 x 2 x 2 x 3 x 3 = 72, the LCM
√9 x 2 x (8 - 4) = 3 x 2 x 4 = 24
x+x^2=72x^2 +x -72=0 (x+9)(x-8)=0 x=-9 or x=8
1 Through 9 to 9 Through 1:1 x 8 + 1 = 912 x 8 + 2 = 98123 x 8 + 3 = 9871234 x 8 + 4 = 987612345 x 8 + 5 = 98765123456 x 8 + 6 = 9876541234567 x 8 + 7 = 987654312345678 x 8 + 8 = 98765432123456789 x 8 + 9 = 987654321Sequential Input to All 1's:1 x 9 + 2 = 1112 x 9 + 3 = 111123 x 9 + 4 = 11111234 x 9 + 5 = 1111112345 x 9 + 6 = 111111123456 x 9 + 7 = 11111111234567 x 9 + 8 = 1111111112345678 x 9 + 9 = 111111111123456789 x 9 + 10 = 1111111111All 1's to a Numeric Palindrome:1 x 1 = 111 x 11 = 121111 x 111 = 123211111 x 1111 = 123432111111 x 11111 = 123454321111111 x 111111 = 123456543211111111 x 1111111 = 123456765432111111111 x 11111111 = 123456787654321111111111 x 111111111 = 12345678987654321
Since 8 is 2 x 4, 9 x 8 is 2 x 9 x 4
8 x (9 - 3) 4^2 (9 - 3) - 4^2 12-4^2 4 x 8 =32
The answer is '72'. However, learn your '8' times table and your '9' times table. of multipolication. 8 times 8 x 1 = 8 8 x 2 = 16 8 x 3 = 24 8 x 4 = 32 8 x 5 = 40 8 x 6 = 48 8 x 7 = 56 8 x 8 = 64 ( 8^2 ; 8 squared) 8 x 9 = 72 ( as answered) 8 x 10 = 80 8 x 11 - 88 8 x 12 = 96 And 9 times 9 x 1 = 9 9 x 2 = 18 9 x 3 = 27 9 x 4 = 36 9 x 5 = 45 9x 6 = 54 9 x 7 = 63 9 x 8 = 72 ( as answered) 9 x 9 = 81 ( 9^2 ; 9 squared) 9 x 10 = 90 9 x 11 = 99 9 x 12 = 108
9 x 8! = 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1So, 9 x 8! = 9! = 362,800
9/8 x 2 = 18/8 = 9/4 or 2 and 1/4
2 x 2 x 2 = 8 3 x 3 = 9 2 x 2 x 2 x 3 x 3 = 72, the LCM
√9 x 2 x (8 - 4) = 3 x 2 x 4 = 24
3 x 3 = 9 2 x 2 x 2 = 8 2 x 7 = 14 2 x 3 = 6
9:2 :: x:16 We note that 16 = 2 x 8 So to bring to equivalence . the 'x' is 9 X 8 = 72 Hence 9:2 :: 72:16 Note the use of colons for 'is to', and 'as'.
8 x (9 - 8 + 2) = 24.
The prime factorization of 8 is 2 x 2 x 2. The prime factorization of 9 is 3 x 3. 8 x 9 = 72 2 x 2 x 2 x 3 x 3 = 72
18 = 9 x 2, so LCM of 18 & 9 is 18. 8 = 2 x 2 x 2; so 18 & 8 share a common factor of 2, so the LCM = 18 x 2 x 2 = 72.
