5x^(-1) or 5/x.

Step-by-step explanation: The equation given is (5*x^2)/x^3 and we are supposed to solve it for x = 2. First. we simplify the equation. Since we have x^2  in the numerator and x^3 in the denominator, using the equation a^x/a^y = a^(x - y) we find that we get 5*x^(-1) we can leave it like this or simplify it to 5/x, since negative exponents mean fractions.

10 * 563.67 = 5636.7

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
