I'll do 12:
[tex]\frac{6^{7} }{6^{5}}[/tex] = a long fraction that it gives me an error if i try to put into the equation tool.
For each 6 that exists on both the numerator and denominator, we can cancel them out and find the answer to be 6^{2}..
...or we can simply treat 6^{7} / 6^{5} as 6^{7 - 5} because dividing means to subtract the exponents (the numbers have the same bases), and get the same answer, 6^{2}.
Hope this helps! :)
