Using PEDMAS, you would divide I/2 first, then add 2 to that and subtract I from the equation. It all varies on what "i" is, however.

The solution to the problem is as follows:
2+i/2−i

=(2+i/2−i)∗(2+i/2+i)

=(4+4i−1/5)

=(3/5<span>)

Select the equation in which you use the inverse property of multiplication to find the solution.

loris [4]

Given:

Equations using properties.

To find:

The equation which use the inverse property of multiplication.

Solution:

<u>Inverse property of multiplication:</u>

<em>The product of any number and its reciprocal is always 1.</em>

Let us select the option which uses inverse property of multiplication.

Option A: $\left(\frac{3}{4} \cdot \frac{4}{3}\right)+7=8$

Inverse of $\frac{3}{4}$ is $\frac{4}{3}$ . Their product is 1.

$$\frac{3}{4} \cdot \frac{4}{3}=1$

This equation uses the inverse property of multiplication.

Option B: $\left(-\frac{7}{8}+\frac{7}{8}\right)+4=4$

Inverse of $\frac{-7}{8}$ is $\frac{8}{-7}$

So, it is not true equation.

Option C: $(-5 \cdot 0)-9=-9$

Inverse of $-5$ is $-\frac{1}{5}$ .

So, it is not true equation.

Option D: $\left[7 \cdot\left(\frac{5}{7}-\frac{4}{7}\right)\right]+8=9$

Here also inverse property is not used.

So, it is not true equation.

Hence the equation use the inverse property of multiplication is

$$\left(\frac{3}{4} \cdot \frac{4}{3}\right)+7=8$ .
