Question

Find the value of x.​

Answer 1

Answer:

x=-5

Step-by-step explanation:

$( \frac{7}{8} )^{ - 8} \times ( \frac{7}{8} )^{ 3} = ( \frac{7}{8} )^{ x} \\ ( \frac{7}{8} )^{ - 8 + 3} = ( \frac{7}{8} )^{ x} \\ ( \frac{7}{8} )^{ - 5} = ( \frac{7}{8} )^{ x} \\ - 5 =x \\ x = - 5 \\ remember = > {a}^{m } \times {a}^{n} = {a}^{m + n}$
