Step 1: Use the change of base formula

To solve for log2(320), you can use the change of base formula, which states that
logb(a) = ln(a) / ln(b). You can use either the natural logarithm (ln) or the common logarithm (log) for the new base. Using the natural logarithm, the expression becomes:

log2(320) = ln(320) / ln(2)

Step 2: Calculate the values and divide

Next, calculate the natural logarithm of 320 and 2, and then divide the results.

  • ln(320) ≈ 5.768321
  • ln(2) ≈ 0.693147

Now, divide the two values:

5.768321 / 0.693147 ≈ 8.321928

Answer:

The base 2 logarithm of 320 is approximately 8.321928 or log2320 = 8.321928.

Notes:
i) e and pi are accepted values.
ii) 1.2 x 103 should be entered as 1.2e3 and
iii) 1.2 x 10-3 as 1.2e-3

Frequently Asked Questions About Log2(320)

What Is The Base 2 Logarithm Of 320?

The base 2 logarithm of 320 is approximately 8.321928.

In mathematical notation: log2(320) = 8.321928

How Do You Calculate Log2(320)?

To calculate log2(320), use the change of base formula:

log2(320) = ln(320) / ln(2)

Where ln is the natural logarithm. This gives us:

5.768321 / 0.693147 ≈ 8.321928

What Does Log2(320) = 8.3219 Mean?

This means that 2 raised to the power of 8.3219 equals 320:

28.3219 = 320

In other words, if you multiply 2 by itself 8.3219 times, you get 320.

What Is Special About Base 2 Logarithms?

Base 2 logarithms are commonly used in computer science and information theory because computers work in binary (base 2).

They tell us how many times we need to divide a number by 2 to reach 1, which is useful for analyzing algorithms and data structures.

For example: log2(320) = 8.321928 means 320 = 28.321928

Can I Calculate Other Values Using This Base?

What is logarithm?

A logarithm is the power to which a number must be raised in order to get some other number. In other words, the logarithm tells us how many of one number should be multiplied to get another number.

For example:

  • The base 2 logarithm of 4 is 2, because 2 raised to the power of 2 is 4:
  • log3 9 = 2, because 32 = 9

This is an example of a base-3 logarithm. We call it a base-3 logarithm because 3 is the number that is raised to a power.

The most common logarithms are natural logarithms and base 10 logarithms. There are special notations for them:

  • A base 10 log is written simply log.
  • A natural logarithm is written simply as ln.

So, the notation log alone means base ten logarithm and notation ln, means natural log.

Basic Log Rules

  • logb(x·y) = logb(x) + logb(y)
  • logb(x/y) = logb(x) - logb(y)
  • logb(xy) = y·logb(x)
  • logb(x) = logk(x)/logk(b)
