True and false

IF A is 5*5 matrix 

then

  1. det(4$A^{3}$)=$4^{5}det(A^{3}))$
  2. det($(4A)^{3}$)=$det(4^{3}A^{3}))$

i think both are true ??

Invertible Matrix
Let A be a $5 × 5$ invertible matrix with row sums $1$. That is $\sum_{j=1}^{5} a_{ij} = 1$ for $1 \leq i\leq 5$. Then, what is the sum of all entries of $A^{-1}$.
