Write an expression showing a ÷ 2 without the use of the division symbol. what can we determine from the model?

The required expression is shown below

Step-by-step explanation:

Consider the provided information.

Write an expression showing a ÷ 2 without the use of the division symbol.

Here the a ÷ 2 shows that the variable a is divided by 2.

The model for this expression is shown in figure below:

We can rewrite the expression in fractional form as shown:

If we write division expressions using the division symbol, we represent  dividend ÷ divisor.

In fractional form it will look like:

Step-by-step explanation:

given, a ÷ 2

division symbol is  given as ' ÷ '

the expression above can also be shown  without division symbol as

                           =     a/2

we can determine from the model is that the expression

            a ÷ 2 will be equal to  a/2

the diagram attached below will show  a ÷ 2 or a/2

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
