Question

Pls solve showing steps, thanks! 7^4n+19/7^3n-1•7^n+20

Answer 1

Answer:

This expression can be simplified to 1

Step-by-step explanation:

$\frac{7^{4n + 19}}{7^{3n - 1}\times{7^{n + 20}}}\\\\= \frac{7^{4n + 19}}{7^{3n - 1 + n + 20}}\\\\= \frac{7^{4n + 19}}{7^{(3n + n) + (20 - 1)}}\\\\= \frac{7^{4n + 19}}{7^{4n + 19}}\\\\= 1$
