Answer 1

$\sf \color{blue}Solution$

$\left(\begin{array}{c} \dfrac{8}{3} \\ \end{array}\right) ^{ - 5} \times \left(\begin{array}{c} \dfrac{8}{3} \\ \end{array}\right) ^{ - 11} = \left(\begin{array}{c} \dfrac{8}{3} \\ \end{array}\right) ^{ \sf \: 8m}$

Having same base therefore use the so called formula - aᵐ × aⁿ = a ᵐ+ⁿ. Also, comparing exponential powers at the same time.

$\sf - 5 + ( - 11) = 8m$

$\sf - 16 = 8m$

$\bf \: m \: = - 2$
