Answer:

Step-by-step explanation

This is because the 'principal square root' means the positive square root of a certain number, and so √16 = 4 × 4, making 4 the answer. This has a certain term for it as √16 could equal -4 also (-4 × -4 = 16).

Step-by-step explanation:

4b + 8 = 20

Subtract 8 from both sides

4b + 8 - 8 = 20 - 8

4b = 12

Now divide both sides by 4

4b/4 = 12/4

b = 3

Check:

LHS = 4b + 8

= 4*3 + 8

= 12 + 8

= 20 = RHS
