The value of the logarithmic expression log798 is 2.9.

What is a logarithm?

A logarithm is the exponentiation inverse function that can be expressed by the exponent or power to which a base must be raised to yield a number.

Write the value of the logarithmic expression log798 by using the logarithmic product property.

log798= log 19 + log 42

The factors of the value 798 are calculated as:-

798 = 2 x 3  x 7 x 19

798= 19  x  42

Use the logarithmic property:- [ log ab = log a + log b ] to write the value of the given expression log 798.

log 798 = log (19 x 42)

Apply the property:-

log 798  = log 19 + log 42

log 798  = 1.27 + 1.62

log 798  = 2.9

Therefore, the value of the expression log 798 will be 2.9.
