Compare 3 x 10^-25 and 4.5 x 10^-24, which number is the greatest. Explain your reasoning for the answer you choose.

4.5 x 10^-24

Step-by-step explanation:

because 3 x 10^-25 is 0000000000000000000000000.3    

and 4.5 x 10^-24 is 0000000000000000000000004.5 its just greater

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
