Question

ecuaciones exponenciales

Answer 1

$2^{x+ 2} = 16\\ \\ 2^{x+ 2} = 2^{4} \\ \\ x+2 = 4\\ \\ x = 4 - 2 \\ \\ x = 2$

$(3^{2})^{^{x - 5} } = 81\\ \\ 3^{2x-10} = 3^{4} \\ \\ 2x - 10 = 4\\ \\ 2x = 4 + 10\\ \\ 2x = 14\\ \\ x = 14/2\\ \\ x = 7$

$(2^{x-1})^{^{2} } = 64\\ \\ 2^{2x-2} = 2^{6}\\ \\ 2x - 2 = 6\\ \\ 2x = 6 + 2\\ \\ 2x = 8\\ \\ x = 8/2\\ \\ x = 4$
