Raising a number to an exponent means multiplying it by itself that many times, so 2 to the power 5 is 2 times 2 times 2 times 2 times 2, which is 32. The browser-based scientific calculator evaluates exponents along with roots and other functions, entirely in your browser with nothing uploaded.
An exponent, or power, tells you how many times to multiply the base by itself. In 2 to the power 5, the base is 2 and the exponent is 5, so the result is 2 multiplied by itself five times, which is 32. A power of 2, like 3 squared, means 3 times 3, or 9. A negative exponent means one divided by the positive power, and an exponent of zero always gives 1.
For large exponents or non-integer powers, doing the multiplication by hand is slow and error-prone. The scientific calculator evaluates exponents together with square roots, logarithms, trigonometric functions and the constants pi and e, using parentheses so a full expression stays unambiguous. It runs in your browser, keeping your input private.
Any nonzero number raised to the power of zero is 1.
A negative exponent means one divided by the number raised to the matching positive power.
No. The scientific calculator runs entirely in your browser.
