Answer 2

$\bf{\underline{Question:-}}$

• $\sf 4^n +5^n = 9^n$

$\bf{\underline{To\:Find:-}}$

• Value of n = ?

$\bf{\underline{Solution:-}}$

$\bf → 4^n + 5^n = 9^n$

$\bf → 9^n = 9^n$

• ( base are equal )

Now,

• comparing the exponent

$\sf→ n = n$

$\sf → n/n = 0$

$\sf → n = 0$

$\bf{\underline{Hence:-}}$

• The required value of n is 0
