Answer 2

Answer:

x = 4

Step-by-step explanation:

${9}^{x} \div {9}^{ - 4} = {9}^{8}$

${9}^{x - ( - 4)} = {9}^{8}$

Why ? Because...

${m}^{a} \div {m}^{b} = {m}^{a - b}$

As bases are same, we can evaluate x now,..

$x \: - ( - 4) = 8$

$x \: + 4 = 8$

$x \: = 8 - 4$

$x \: = 4$

therefore, x = 4...
