Aug 17, 2023 · This online calculator puts calculation of both exponents and radicals into exponent form. To calculate exponents such as 2 raised to the power of 2 you would enter 2 raised to the fraction power of (2/1) or 22 1 2 2 1. To calculate radicals such as the square root of 16 you would enter 16 raised to the power of (1/2).
The exponent of a number says how many times to use the number in a multiplication. In this example: 82 = 8 × 8 = 64. In words: 8 2 could be called "8 to the second power", "8 to the power 2" or simply "8 squared". Another example: 53 = 5 × 5 × 5 = 125.
If a fraction is raised to the power of a fraction, for eg. if 2/7 is raised to the power of 7/9, then 2/7 would be under the root of 9, and 2/7 would be raised to the power of 7 when it's under. HOPE THIS HELPS, THANK YOU

- I think the pattern goes something like this: 2^3 = (2.2.2) = 8 2^2 = (2.2) = 4 2^1 = (2) = 2 2^0 = ? (This is tricky and is covered in later video...
- 3:00. He is correct. (27)^2/3=the cube root of 27 and square it=3^2=9
- If my brain does not fail me I think that's correct. The answer is x^2.
- (1/2)^7 is telling you to multiply: 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 * 1/2 Hope this helps.

May 3, 2024 · Assume our fraction is equal to -2/5. Enter -2 in the numerator and 5 in the denominator box (signs the other way round work as well). Enjoy the result displayed by our fractional exponent calculator!
If an exponent of a number is a fraction, it is called a fractional exponent. Exponents show the number of times a number is replicated in multiplication. For example, 4 2 = 4×4 = 16. Here, exponent 2 is a whole number. In the number, say x 1/y, x is the base and 1/y is the fractional exponent.
Raising fractions to a power is a fundamental math skill. To do this, simply multiply the numerators and denominators separately. For example, when raising a fraction like 2/3 to the third power, multiply the numerators (2 × 2 × 2 = 8) and the denominators (3 × 3 × 3 = 27) to get the result 8/27.

How to solve powers of fractions. To raise a fraction to an exponent, raise both the numerator and denominator to that exponent. *\left (\dfrac {a} {b}\right)^n=\dfrac {a^n} {b^n}*. A particular case is when the exponent is 2. To square a fraction, square both the numerator and the denominator. *\left (\dfrac {a} {b}\right)^2=\dfrac {a^2} {b^2}*.
