Question

*If ‘m’ is the geometric mean of 12 and 3 then find the value of ‘m’.*
1️⃣ 6
2️⃣ 9
3️⃣ 36
4️⃣ 15​

Answer 1

Answer:

6

Step-by-step explanation:

geometric mean of  

3  and  12

=√3*12

=√3*3*2*2

=3*2

6

Answer 2

Given:

Consider the given geometric mean m of 12 and 3

Find:

Need to find the value of m

Solution:

We have the geometric mean formula of two numbers a and b

geometric mean = $\sqrt{a.b}$

Therefore

m = $\sqrt{12\times 3}$

m = $\sqrt{36$

m = 6

Hence the correct option is (1).
