Answer: trivial solution is the only solution to Ax = 0, therefore columns must be linearly independent.

Step-by-step explanation: Recall that the columns of A are linearly independent if and only Ax = 0 had only the trivial solution. Since Ax = b has at most one solution, therefore the only solution to Ax = 0 is the trivial solution and the column vectors must be linearly independent.

mamaluj [8]

Answer:

\log x =\frac{\log 117}{-12} this should be what youre asking

Step-by-step explanation:

  • this is it
  • x^{-12} =117\\ \log x^{-12} =\log 117\\ -12\log x=\log 117\\\log x =\frac{\log 117}{-12}
