(8+3) x 4 = 44
(9+7) x 2 = 32
75 / (8+7) = 5
the answer is 5
Congratulations man you won the quiz
First you take the bottom left corner and top corner and add them together. Take the sum of that number and multiple by the bottom right corner to get the big number in the center. Like this:
3+8 = 11, 11 x 4 = 44
9+7 = 16, 16 x 2 = 32
8+7 = 15, 15 x 5 = 75
The missing number is 5
Congratulations mate you are also among the winners to this quiz
Thanks! :)
you add up the numbers in the left and the upper corner. then you multiply this number with the Number in the right corner. And then you have the number in the middle :)
8+3 =11; 11 * 4=44
7+9=16; 16 * 2=32
7+8=15; 15 * ?=75
you have simply to divide the Number in the middle(75) through the number you get, when you add up the left and the upper corner (15) to get the number in the right corner.
The number in the right corner is 5.
:)
Waw your explanation really impress me :)
@mathematrix has set 0.150 SBD bounty on this post!
What is a bounty exactly?
A bounty is money sent to a post to be distributed to the users commenting on it. It provides a way to reward users directly and works in addition to the steem/sbd they receive from the blockchain. It works independently of SteemPower.
You create a bounty by sending any amount of sbd/steem to @steem-bounty together with a post-url in the memo.
How can I earn a bounty Users are then competing for the bounty by writing their answers to the post in comments that will achieve upvotes from the community and especially the bounty creator. The money of the bounty gets distributed to all top level comments of the post at the same time when the post is paid out (7 Days after it was written). How much everyone gets depends on the votes the comments received. The sender of the bounties votes are weighted higher so that she decideds where 80% of the bounty money goes and all other votes determine the rest.@steem-bounty does all of this for you automatically. You can use this service to automatically pay out a challenge, ask a hard question or simply to reward the people that interact with you.

Congratulations to the following winner(s) of the bounty!
8+3 =11
11*4 = 44
if we use that logic on the last one
then
7+8=15
75/15=5
so the ? is 5
5
An alternate answer: the product of every number in the triangle has nine prime factors.
8 * 44 * 3 = 2^5 * 3 * 11, which is 7 prime factors. The least number that can be multiplied to give 9 prime factors is 4.
7 * 32 * 9 = 2^5 * 3^2 * 7 , which which is 8 prime factors. The least numbers that can be multiplied to give 9 prime factors is 2.
7 * 75 * 8 = 2^3 * 3 * 5^2 * 7, which is 7 prime factors, again. So we should multiply by 4 to get two additional prime factors.
Therefore, the question mark should obviously be 4.
The number that must replace the question mark is 5.
In the case of the three triangles, first the top vertex is added next to the left vertex, then the result is multiplied by the right vertex. This is how you get the value.
