Math Problem Statement

Convert the base-4 number 101313 to base-10.

Solution

The given number is in base-4, specifically "101313". To convert this base-4 number to base-10, we follow the procedure of expanding it using powers of 4.

The base-4 number "101313" is represented as:

1013134=1×45+0×44+1×43+3×42+1×41+3×40101313_4 = 1 \times 4^5 + 0 \times 4^4 + 1 \times 4^3 + 3 \times 4^2 + 1 \times 4^1 + 3 \times 4^0

Now let's calculate each term:

1×45=1×1024=10241 \times 4^5 = 1 \times 1024 = 1024 0×44=0×256=00 \times 4^4 = 0 \times 256 = 0 1×43=1×64=641 \times 4^3 = 1 \times 64 = 64 3×42=3×16=483 \times 4^2 = 3 \times 16 = 48 1×41=1×4=41 \times 4^1 = 1 \times 4 = 4 3×40=3×1=33 \times 4^0 = 3 \times 1 = 3

Adding all these up:

1024+0+64+48+4+3=11431024 + 0 + 64 + 48 + 4 + 3 = 1143

Thus, the base-10 equivalent of the base-4 number "101313" is 1143.

Would you like any more details or have any other questions? Here are some related questions to further explore the topic:

  1. How do you convert other base numbers (like base-2 or base-8) to base-10?
  2. What is the process of converting a base-10 number to base-4?
  3. How would the base-4 number system be used in computing applications?
  4. Why does the base-4 system use only the digits 0, 1, 2, and 3?
  5. How can you quickly determine the place value in different bases?

Tip: When converting numbers from one base to another, breaking them down step by step and expanding them using powers of the base makes the process much easier.
