Answer 1

Answer:

  sqrt(ac)

±----------  = b

    3c

Step-by-step explanation:

a= 9b^2 c

Divide each side by 9c

a/9c = 9b^2c / 9c

a/9c= b^2

Take the sqrt of each side

±sqrt(a/9c) = sqt(b^2)

Remember that sqrt (xy) = sqrt(x) sqrt(y)

±sqrt(a/c) * 1/ sqrt(9) = b

±sqrt(a)     1

--------- * ------ = b

sqrt(c)     3

Multiply  by sqrt(c)/ sqrt(c)

±sqrt(a)     sqrt(c)

--------- * -----------   = b

sqrt(c)     3sqrt(c)

±sqrt(ac)

----------  = b

3c
