About this deal

Let's get our terms nailed down first and then we can see how to work out what 6 to the 20th power is. On most Snellen charts, the smallest letters correspond to 20/10 (6/3) visual acuity. If you have 20/10 (6/3) visual acuity, your eyesight is twice as sharp as that of a person with normal (20/20) vision. Is it possible to see better than 20/20 (6/6)?

Because of the broader nature of the word “vision,” what is commonly called “20/20 (6/6) vision" should really be called "20/20 (6/6) visual acuity" or “20/20 (6/6) eyesight.” What is 20/20 or 6/6?Before we begin, let's revisit some basic fraction terms so you understand exactly what we're dealing with here: Although visual acuity testing is very useful to determine the relative clarity of your eyesight in standardised conditions, it isn't predictive of the quality of your vision in all situations. So you want to know what 6 to the 20th power is do you? In this article we'll explain exactly how to perform the mathematical operation called "the exponentiation of 6 to the power of 20". That might sound fancy, but we'll explain this with no jargon! Let's do it. What is an Exponentiation? Only light that is focused on a very small and highly sensitive portion of the central retina (called the macula) influences visual acuity measurements obtained during an eye exam.

Visual acuity is the clarity of your eyesight, measured by your ability to identify letters or numbers on a standardisedeye chartfrom a specific viewing distance.

The single big "E" at the top of most Snellen eye charts corresponds to 20/200 (6/60) visual acuity. If this is the smallest letter size you can discern with your best corrective lenses in front of your eyes, you are considered legally blind.

Vision is a broader term than visual acuity or eyesight. In addition to clarity of sight or simply a description of the ability to see, the term "vision" all interactions between the eyes and the brain, and all neurological processes that take place in the brain to make the sense of vision possible. A good case could be made that "normal" visual acuity today is an ability to identify letters that are a bit smaller than those on the 20/20 (6/6) line of a traditional Snellen eye chart. The term "20/20" (or 6/6 when measured in metres as used in Australia and New Zealand) and similar fractions (such as 20/60 (6/18), 20/40 (6/12) etc.) are visual acuity measurements. They also are called Snellen fractions, named after Herman Snellen, the Dutch ophthalmologist who developed this eyesight measurement system in 1862. To work this out we'll use the whole number we calculated in step one (3) and multiply it by the original denominator (6). The result of that multiplication is then subtracted from the original numerator:Now that we have our whole number for the mixed fraction, we need to find our new numerator for the fraction part of the mixed number. Step 2: Get the new numerator So basically, you'll either see the exponent using superscript (to make it smaller and slightly above the base number) or you'll use the caret symbol ( Now let's go through the steps needed to convert 20/6 to a mixed number. Step 1: Find the whole number
