Rewrite the equation so that the bases are the same; then the exponents will be the same.

8%5Ex+=+%282%5E3%29%5Ex+=+2%5E%283x%29
1%2F32+=+1%2F2%5E5+=+2%5E%28-5%29

So

2%5E%283x%29+=+2%5E%28-5%29
3x+=+-5
x+=+-5%2F3

+8%5Ex=1%2F32+
+%282%5E3%29%5Ex=1%2F2%5E5+
+2%5E%283x%29=2%5E-5+......if bases same, exponents are same too
+3x=-5+
+x=-5%2F3+
