Express 53 = x as a logarithmic equation.

Step-by-step explanation:

Using logarithmic rule:

Given the equation:

Taking log with base 5 both sides we have;

Apply the logarithmic rule:

or

Therefore, as a logarithmic equation is,

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3

you,
