What is the value of the expression 0.5 power 2

the value of 0.5 to the second power is 2.5

Step-by-step explanation:

the reason it is 2.5 is because when you have any power whether it be a large number like 12 or a small number 4 you will only be multiplying the number by the power such a 5 to the 3rd power you would multiply 5 by itself 3 times geting 125.

so in this case it is 5 to the 2nd power = 0.5*0.5=2.5
