Xˆ8 ÷ xˆ2 fully factorised

Step-by-step explanation:

x^8/x^2= = x^6

when you divide same base and different powers, you subtract the powers

Step-by-step explanation:

There are 2 ways that you can do this problem. The first is just to factor everything and cancel.

x * x * x * x *x * x *x *x

x * x

Two of the xs on the top cancel leaving you with the number 1 on the bottom

x * x * x * x * x * x = x^6

This is one of your answers.

The other is you can notice you get the same thing by subtracting powers.

x^(8 - 2) = x^6

I'm not sure which answer is expected. I would guess the second one.

g

step-by-step explanation:

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.
