The pH scale measures the acidity or alkalinity of a solution on a logarithmic scale, where each whole number change represents a tenfold difference in hydrogen ion concentration. For example, a solution with a pH of 3 has ten times more hydrogen ions than a solution with a pH of 4, which corresponds to a concentration of (10^{-3}) moles per liter compared to (10^{-4}) moles per liter. Thus, pH values are inversely related to the concentration of hydrogen ions, expressed in powers of ten.

How does a scale factor relate to a scale factor?

When subtracting or adding numbers in scientific notation why do the exponents gave to be the same?
When adding or subtracting numbers in scientific notation, the exponents must be the same to ensure that the terms are expressed in the same scale. Scientific notation represents numbers as a product of a coefficient and a power of ten, so if the exponents differ, the values are on different scales, making direct addition or subtraction impossible. By adjusting the numbers to have the same exponent, you can accurately combine the coefficients before simplifying the result back into proper scientific notation.
What are some real life application of exponents and logarithms?
Logarithms are used in the royal navy in sonars They are but it's far wider than that. The application you mean is the "decibel", the 10X or 20X logarithm of the ratio of two signal intensities or powers - not just in military and commercial sonar, but in acoustics generally, and in electrical engineering such as amplifier design. The Richter Scale and the magnitude scale of star brightness are logarithmic. Common and hyperbolic logarithms crop up in many places - the latter control the expansion or compression of gas in an engine or compressor cylinder, for example. Exponents also facilitate handling very large & very small numbers by turning them into multiples of plus or minus powers of 10.
How do you write 2.83 billion in numbers?
As I use the long scale (based on powers of a million) as used in countries like Europe, I write it as 2,830,000,000,000 Others, however, use the short scale (based on powers of a thousand plus one) as used in countries like USA and write it as: 2,830,000,000
How does scale factor relate to perimeter?
Scale factor and perimeter are related because if the scale factor is 2, then the perimeter will be doubled. So whatever the scale factor is, that is how many times the perimeter will be enlarged.
What computing tool consisted of two numbered rules which when slid against one another could add the length of one number to another?
That sounds like a description of a "slide-rule". When the numbers are spaced by a logarithmic scale, they can be used to perform multiplications due to the fact that when two numbers are represented as powers of the same base number, you can find the product of the two numbers by adding the exponents.

How do ratios and fractions relate to scale?
They both can be divided.
How is the Richter Scale used with connection with exponents?
The Richter Scale is a logarithmic scale that measures the magnitude of earthquakes. Each whole number increase on the Richter Scale represents a tenfold increase in amplitude and approximately 31.6 times more energy release, akin to how exponents increase rapidly with each whole number. This scale allows for easier comparison of earthquake magnitudes by condensing a wide range of values into a more manageable scale.
How degrees relate to Fahrenheit?
A degree is a step on the Fahrenheit scale.
When you add numbers what do you do to the exponent?
You can only add numbers if they have the same exponent. If not, you need to scale them so that they do. Add the mantissae of the numbers (these are the bits before the exponents). That is followed by the common exponent. For example: 3.1*102 + 3.6*103 = 0.31*103 + 3.6*103 (now the exponents are the same) = (0.31 + 3.6) *103 or 3.91*103 In this particular example, it is easy enough to check the answer: 3.1*100 + 3.6*1000 = 310 + 3600 = 3910 = 3.91*1000 = 3.91*103
