Chapter 2: Q60. (page 102)

Find the value of n. Then name the property used in each step. (Lesson 1-3)

25n=25

Short Answer

Expert verified

The value of n is 1. The property used is multiplicative identity property.

Step by step solution

01

Step 1. State the property.

The multiplicative identity property states that for any number a, the product of aand 1is a.

So, a鈰�1=a.

02

Step 2. Write the given equation.

The given equation is 25n=25.

03

Step 3. Solve the given equation.

Put a=25in a鈰�1=ato get,

25鈰�1=25

Compare 25鈰�1=25with 25n=25to get,

n=1

So, the solution of the given equation is n=1and the property used is the multiplicative identity property.
