Value of Irrational Number π (Part 1)

Click For Summary
SUMMARY

The value of the irrational number π, accurate to ten decimal places, is 3.1415926535. The discussion centers around determining how many decimal places the quantity (4/3)^4, which equals 256/81, agrees with π. Participants explore whether this can be calculated without a calculator, suggesting the use of long division for manual computation. The original question was edited for clarity to avoid confusion among participants.

The value of irrational number π, correct to ten decimal places (without rounding), is 3.1415926535. By using your calculator, determine to how many decimal places the following quantity [(4/3)^4] agrees with π.

The value used for π in the Rhind papyrus, an ancient Babylonian text written about 1650 B.C. is (4/3)^4.

I was wondering if this question can be answered without a calculator. Can we show that (4/3)^4 in terms of decimal places agrees with pi?

Then this should be said in the original question to not make people guess.

You can use long division to compute $$\left(\frac43\right)^4=\frac{256}{81}$$ to a few decimal places.
