There should be a negative button on your calculator, separate from the minus button. Press that button before pressing the buttons for the numbers of the exponent.
Assuming the calculator can do exponents, take the number and raise it to the power of 1/2.
Not sure about the Casio, but most calculators which have capability to handle complex numbers should be similar. Input the complex number according to however you normally do that, then raise to a power. In the case of roots, you want to raise to a reciprocal power: Square root is 0.5 power, cube root is 1/3 power, fourth root is 0.25 power, etc
When you raise a number to the third power, you get the 'cube' of the original number.
Multiply the number by itself three times. For example: if you want to raise the number 2 to the third power then 2^3=2x2x2=8.
When you raise a number to the third power, you get the 'cube' of the original number
(-1)^3 = -1 Every negative number raised to the odd power is a negative number.

If your calculator is advanced, like the TI-84, there is an exponent button you can hit. Then, just Type negative and the exponent. If it is a simpler calculator, like a four-function calculator, there IS a way. By raising a number to a negative exponent, you are saying that one is being divided by that number to the positive version of that power. Ex: 5^-8 = 1/(5^8). To do this, divide one by the base, then raise it to the exponent, making sure that the exponent is POSITIVE. Also be careful that the entire denominator is in parentheses, just in case.
If your calculator has an exponentiation function, simply raise the number to the power of .5 Remember this trick: the nth root of X = X ^ (1/n)
Enter the number you wish to find the square root of, and then raise it to the power of one-half. x^0.5 = sqrt(x)
#include <math.h> and link to the math library, then you can use pow(base, exponent).
(-2)2 = (-2)(-2) = 4 (when we raise a negative number to an even power, the result is always positive) (-2)3 = (-2)(-2)(-2) = -8 (when we raise a negative number to an odd power, the result is always negative) (-3)4 = 81 (-3)5 = -243
because you cant raise a number negatively exponentially
Yes, most 4-function calculators have a power or exponent button denoted by a "^" symbol. You can use this button to raise a number to a power.
To raise something by the power of negative one, take the reciprocal of the number. In this instance, -3/4-1 = -4/3 or negative four thirds. Expressed as a decimal, this is equal to -1.3 recurring (that is, -1.3333...)

The answer to your question is (2x + 2y)^-1 = 1/(2x + 2y)^1. When you raise a number to a negative power, you can rewrite it by dividing one by the original number with the negative sign dropped from the exponent. Because the power here is 1, you can rewrite the answer again to 1/(2x + 2y) since any number raised to the power of 1 is simply the number itself. You can't add 2x and 2y because they are two different variables.
