Final answer:
To make b the subject of the formula a = √b +6, subtract 6 from both sides and then square both sides of the equation. The equation with b as the subject is b = (a - 6)^2.
Step-by-step explanation:
To make b the subject of the formula a = √b +6, we need to isolate b on one side of the equation. Let's go step by step:
- First, subtract 6 from both sides of the equation:
- a - 6 = √b
- Square both sides of the equation to eliminate the square root:
- (a - 6)^2 = (√b)^2
- (a - 6)^2 = b
Therefore, the final equation with b as the subject is b = (a - 6)^2.
