# If a PH changes by 1 what is the hydrogen ion in a logarithmic scale?

the hydrogen ion conc=0.1

# What is the logarithm of log -1?

Assuming you are asking about the natural logarithms (base e): log (-1) = i x pi therefore log (log -1) = log (i x pi) = log i + log pi = (pi/2)i + log pi which is …approximately 1.14472989 + 1.57079633 i

# Why use a natural base logarithm?

The natural base, e, 2.718281828..., was selected because the derivatived/dx ex is equal to x. This simplifies many calculations, derivatives, integrals, etc. Additional: This… base is used because there is a series (of terms) for powers of (e), therefore, powers of any value can be found just by plugging in values in the series.

# The base 10 logarithm is called the logarithm?

Base 10 logarithms are called "common logarithms".

# What is log 1 to the base 1?

acording to me the value is 0 because the value of log 1 at any base is always 0.

# What is the base 10 logarithm called?

The base 10 logarithm is called the "common logarithm". * * * * * It is also called the 'Briggsian logarithm', named after Henry Briggs, who introduced his table of logari…thms on base 10 at Oxford in 1624, much to the joy of navigators, astronomers, and others having tedious calculations to perform.

# The base of common logarithms?

The base of common logarithms is ten.

# What is the logarithm of 16 to the base 4?

There are two ways to solve this. One is using the definition of logarithms: solve the equation 4 x = 16. This can be done by inspection, in this case. The other is to use …a change-of-base, to change to a base your calculator can handle. For example, changing to base e: log 4 16 = ln(16) / ln(4)

# What is the logarithm of -1?

Negative numbers don't have logarithms.

# What is the second derivative of the natural logarithm of 1 minus X?

d/dx ln(1-x) = 1/(1-x) d/dx 1/(1-x) = 1-x * d/dx 1 - 1 * d/dx(1-x)/(1-x^2 = 1-x * 0 - 1 * 0 - 1/(1-x)^2 = -1/(1-x)^2 --------------

# Can the base of a logarithm be 0?

No, it is undefined and indeterminate. Log base y of a variable x = N y to the N power = x if y ( base) = 0 then 0 to the N power = x which is always zero (or one in some case…s) and ambiguous. Say you want log base 0 of 50 0 to the N power = 50 cannot be true as 0 to the N is always zero

# What is the notation for a logarithm with base e?

ln() the ln stands for the Latin logarithmus naturali, or natural log in English. loge() is also acceptable but more tedious and rarely used.

# What is the notation for a logarithm with base 10?

The logarithm of a number with base=B is written as [ log B (N) ]. If the base is 10, it's called the "common logarithm" of N and the base isn't written. [ log(N) ]. … If the base is 'e', it's called the "natural logarithm" of N, and written [ ln(N) ].

# Can a logarithmic function have a base of zero?

No. No number can be generated by raising zero to a power. Zero raised to any power is still zero.
