Answer:

$\frac{p^2-25}{p^2-10p+25}$

We can factorise the numerator with the difference of squares formula: $x^2-y^2=(x+y)(x-y)$

-----------------------------

$\frac{p^2-5^2}{p^2-10p+25} =\frac{(p+5)(p-5)}{p^2-10p+25}$

Now we can factorise the denominator:

$\frac{(p+5)(p-5)}{p^2-10p+25} =\frac{(p+5)(p-5)}{(p-5)^2}$

$\frac{(p+5)(p-5)}{(p-5)^2} =\frac{(p+5)(p-5)}{(p-5)(p-5)}$

Cancel out the common factor of (p-5):

$\frac{(p+5)(p-5)}{(p-5)(p-5)} =\frac{(p+5)}{(p-5)}$

We know that:

$x^{a+b}=x^a\cdot x^b$

and:

$(x\cdot y)^a=x^a\cdot y^a$

so:

$3^{x+2}-3^{x}=6^3\cdot3^7\\\\3^x\cdot3^2-3^x=(2\cdot3)^3\cdot3^7\\\\3^x\cdot9-3^x=2^3\cdot3^3\cdot3^7\\\\3^x\cdot9-3^x=8\cdot3^3\cdot3^7\\\\
3^x\cdot9-3^x=8\cdot3^{3+7}\\\\3^x\cdot9-3^x=8\cdot3^{10}\\\\3^x\cdot(9-1)=8\cdot3^{10}\\\\8\cdot3^x=8\cdot3^{10}\quad|:8\\\\3^x=3^{10}\\\\\boxed{x=10}$
