Question

What is the following product assume b (see attached - immediate help needed)

Answer 1

Answer

b

Explanation

The opposite or reverse of square root is squared. When you take a number and the square it, to get the number back you  just find its square root.

For example,

2 × 2 = 4

√4 = 2

∴ so we can use this concept to solve, √b×√b as follows:

√b × √b  = √(b×b)

                = √b²

               = b
