Matrix to the negative 1

WebMultiplying negative exponents For exponents with the same base, we can add the exponents: a -n ⋅ a -m = a -(n+m) = 1 / a n+m Example: 2 -3 ⋅ 2 -4 = 2 - (3+4) = 2 -7 = 1 / 2 7 = 1 / (2⋅2⋅2⋅2⋅2⋅2⋅2) = 1 / 128 = 0.0078125 When the bases are diffenrent and the exponents of a and b are the same, we can multiply a and b first: a -n ⋅ b -n = ( a ⋅ b) -n WebThe proof is by induction on n, the size of the matrix. When n “ 1 (so the matrix has just one entry, a), then trivially 1 “ a ° 0 implies xax “ ax2 ° 0, for all real x , 0. For our induction …
