Determine the value of variables a, b, and c that make each equation true. What is the value of a in this equation? (xa)6 = StartFraction 1 Over x Superscript 30 EndFraction a = What is the value of b in this equation? (x-7)-4 = xb b = What is the value of c in this equation? (x-2)c = x22 c =

a)

b)

c)

Step-by-step explanation:

a)

To find the value of a, we make a the subject of the equation, therefore cross multiplying to get:

b)

Making b the subject of formula in the equation:
