One tool, 5 calculators: raise any base to a power (including negative and fractional exponents), find an nth root, convert to and from scientific notation, and apply exponent rules.
Works with positive, negative, zero, and fractional (decimal) exponents. A fractional exponent is treated as a root.
Enter a base and exponent to begin.
Use n = 2 for square root, n = 3 for cube root, and so on. Negative numbers only have a real root when n is odd.
Enter a number and root to begin.
Enter a standard number and convert it to scientific notation, or enter a coefficient and exponent to convert back to a standard number.
Enter a number to begin.
When multiplying powers with the same base, add the exponents. When dividing, subtract them.
Enter a base and two exponents to begin.
When raising a power to another power, multiply the exponents together: (xᴬ)ᴮ = xᴬˣᴮ.
Enter a base and two exponents to begin.
| Exponent (n) | 2ⁿ | 10ⁿ |
|---|
xᴬ × xᴮ = xᴬ⁺ᴮ
xᴬ ÷ xᴮ = xᴬ⁻ᴮ
(xᴬ)ᴮ = xᴬˣᴮ
x⁰ = 1 (for x ≠ 0)
x⁻ⁿ = 1 ÷ xⁿ
x^(m/n) = ⁿ√(xᵐ)
2 × 2 × 2 × ... (10 times) = 1024
1 ÷ 5² = 1 ÷ 25 = 0.04
The 4th root of 81 = 3 (since 3⁴ = 81)
2^(3×4) = 2¹² = 4096
4.5 × 10⁶
