Simplify 5^2 x 5^9
A. 5^11
B. 5^18
C. 25^11
D. 25^18

A. 5^11

Step-by-step explanation:

(5^2)(5^9)

=5^2*5^9

=(5*5)*(5*5*5*5*5*5*5*5*5)

=5*5*5*5*5*5*5*5*5*5*5

=5^11

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.
