Solve for n:
5%5E%283n%2B6%29+=+%285%5E%282n%29%29%285%5E%284n-6%29%29 On the right side side, apply the rule of exponents:%28a%5En%29%28a%5Em%29+=+a%5E%28n%2Bm%29
5%5E%283n%2B6%29+=+5%5E%282n%2B4n-6%29 Simplify.
5%5E%283n%2B6%29+=+5%5E%286n-6%29 Apply the rule: Ifa%5En+=+a%5Em then: n+=+mfor any positive a not = 1
3n%2B6+=+6n-6 Subtract 3n from both sides.
6+=+3n-6 Add 6 to both sides.
12+=+3n Divide both sides by 3.
n+=+4
Check by substituting n = 4 into the original equation.
5%5E%283%284%29%2B6%29+=+%285%5E%282%284%29%29%29%285%5E%284%284%29-6%29%29 Simplify.
5%5E18+=+%285%5E8%29%285%5E10%29
5%5E18+=+5%5E18
