[tex]3 {}^{a + 1} = 3 {}^{ - a + 7} \\ a + 1 = - a + 7 \\ a + a = 7 - 1 \\ 2a = 6 \\ a = \frac{6}{2} \\ a = 3[/tex]
25
[tex]2a - b = 4 \\ 2a = 4 + b \\ a = \frac{4 + b}{2} [/tex]
[tex] \frac{4 {}^{a} }{2 {}^{b} } = \frac{2 {}^{2a} }{2 {}^{b} } = 2 {}^{2a - b} \\ 2a - b = 2( \frac{4 + b}{2} ) - b \\ = 4[/tex]
[tex] \frac{4 {}^{a} }{2 {}^{b} } = 2 {}^{4} = 16 \\ [/tex]
