Question

p please answer this equation​

Answer 1

Answer:

m = -5

Step-by-step explanation:

$(\frac{-1}{2} )^{19-8}=(\frac{-1}{2})^{-2m} \times(\frac{-1}{2} )$

= $(\frac{-1}{2})^{11}\div\frac{-1}{2}=(\frac{-1}{2})^{-2m}$

= $(\frac{-1}{2})^{11-1}=(\frac{-1}{2})^{-2m}$

= $(\frac{-1}{2})^{10}=(\frac{-1}{2})^{-2m}$

Equating the powers,

$10 = -2m$

⇒  $-2m=10$

⇒  $m = 10 \div(-2)$ = -5

Hope it helps...
