Answer 1

$</p><p>\huge{\fbox{\fbox{\rightarrow{\mathfrak{Answer \: - }}}}}}$

${3}^{x} = {5}^{x - 2}$

This is applicable only when

${3}^{0} = {5}^{0}$

Hence,

$x = 0$

$x = - 2$

Answer 2

Answer:

x=0 or x=2.

Step-by-step explanation:

We know,

anything to the power 0 is always 1.

So, 3ˣ = 5ˣ⁻² = 1 if the power is 0.

If,

$3^x=1\\\ then\ x=0$.

If $5^x^-^2=1\\\ then\\\ x-2=0\ or\ x= 2.$
