.Hey, I present to you two problems:
To find the Inverse of the matrix in 9.
I have worked out the determinent which is equal to 12, but in 9 that is equal to 3.
Nop. That matrix's determinant is ...., and thus:
I know I have to inverse the determinent in 9 but I am a little unsure about how to do that. But I'm stuck at the line:
Given a matrix:
in 101. work out and find where m = 34 and n = 84.
I have worked out but I'm not sure how to proceed with the other part, I think I must use Euler's formula, but that specifies for two numbers pq that are prime, clearly 34 and 84 are not.
