Formula Information:
Rectangular Tank: Wetted Area = (L ร W) + 2(L ร H) + 2(W ร H)
Cylindrical Tank: Wetted Area = ฯ ร rยฒ + 2ฯ ร r ร H (where r = Width/2)
Spherical Tank: Wetted Area = 4ฯ ร rยฒ (where r = Width/2)
Roots play a vital role in mathematics, helping simplify numbers, solve equations, and analyze complex problems in science and engineering. While square roots (ยฒโx) and cube roots (ยณโx) are commonly used, higher-order roots like the eighth root (โธโx) are important in advanced studies.
Our Eighth Root Calculator allows you to instantly compute the 8th root of any number with accuracy, saving time and effort in manual calculations.
๐น What is the Eighth Root?
The eighth root of a number is a value that, when multiplied by itself eight times, equals the original number. If y=x8, then y8=x\text{If } y = \sqrt[8]{x}, \text{ then } y^8 = xIf y=8xโ, then y8=x
Examples:
- Eighth root of 256 โ 2568=2sinceย 28=256\sqrt[8]{256} = 2 \quad \text{since } 2^8 = 2568256โ=2sinceย 28=256
- Eighth root of 6,561 โ 6,5618=3sinceย 38=6,561\sqrt[8]{6,561} = 3 \quad \text{since } 3^8 = 6,56186,561โ=3sinceย 38=6,561
๐น Formula for the Eighth Root
To calculate the eighth root of a number x: x8=x18\sqrt[8]{x} = x^{\frac{1}{8}}8xโ=x81โ
This can be computed using:
- Scientific calculators
- Programming functions (
x^(1/8)) - Online root calculators

๐น Example Calculation
Find the eighth root of 16,777,216: 16,777,2168=(16,777,216)18\sqrt[8]{16,777,216} = (16,777,216)^{\frac{1}{8}}816,777,216โ=(16,777,216)81โ
Since: 88=16,777,2168^8 = 16,777,21688=16,777,216
โ Result = 8

๐น FAQ โ Eighth Root Calculator
Q1: Can I find the eighth root of a negative number?
A: No, not in real numbers. Since an even root of a negative number is not real, it would require complex numbers.
Q2: Is the eighth root the same as raising to the power of 1/8?
A: Yes, mathematically both are identical.
Q3: Does the calculator handle decimals?
A: Yes, it supports both integers and decimals.
Q4: Whatโs the eighth root of 1?
A: Always 1, since 18=11^8 = 118=1.
Q5: Whatโs the eighth root of 0?
A: Always 0, since 08=00^8 = 008=0.
โ Final Thoughts
The Eighth Root Calculator is a powerful and easy-to-use tool for solving higher-order root problems. By quickly computing โธโx, it saves time, avoids mistakes, and provides instant results useful in mathematics, physics, engineering, and computer science.
