How do I work with a matrix like this??

Homework Statement



How do I go about solving a matrix like this:

[ 3e^4t -2e^3t ]
[ 4e^4t -5e^3t ]

Like how would I get the determinant and stuff? Do I avoid the exponent looking things, or get rid of them somehow??

Please help!

Your matrix doesn't appear to be part of an equation, so there's nothing to solve. You can take the determinant of your matrix the same way you would any 2 x 2 matrix. You know how to multiply e^(at) by e^(bt), right?

Actually...no..

is it exponential multiplication?
 


Do you know how to multiply 2^3 by 2^4?
