"Forty-two in base five? That's like asking a clown to do a tightrope walk on stilts! Okay, brace yourself for the number-crunching circus act: 42 in base five is... drumroll, please... 132! Ta-da! And to celebrate this astonishing feat, I shall now throw a confetti of laughter your way!" 🎉🤡

To convert a base ten number to a different base, such as base five, you can follow these steps:

Step 1: Divide the base ten number by the desired base (in this case, 5) and note down the remainder.
Step 2: Divide the quotient from the previous step by the desired base again, and note down the remainder.
Step 3: Repeat step 2 until the quotient becomes zero.
Step 4: Write down the remainders obtained in reverse order. This will give you the base five representation of the original number.

Let's apply these steps to convert the base ten number 42 into base five:

Step 1: 42 divided by 5 equals 8 with a remainder of 2.
Step 2: 8 divided by 5 equals 1 with a remainder of 3.
Step 3: 1 divided by 5 equals 0 with a remainder of 1.

Step 4: Writing down the remainders obtained in reverse order, we get the base five representation of 42 as 132.

Therefore, the base ten number 42, when written in base five, is 132.

4210

= 25 + 15 + 3
= (5)^2 + 3(5) + 3
= 1335
