Answer :

Step-by-step explanation:

Naturalize log_10 as log

By power rule

log x⁵ + log 20 - log 10

Note

  • log a + log b having same base 10 (or any base just the bases need to be same)equals log(a*b)
  • log_a a = 1

So we conclude

log(20*x⁵)-1

or in a more formal manner

  • log _10 (20x⁵) - 1
