What is the following product?
4V7•4V7•4V7•4V7
A 4(4V7)
B 4v7
C 7^4
D 7

Option (4)

Step-by-step explanation:

Let x =

= (x)(x)(x)(x)

                                 =

                                 = x⁴

Now we substitute the value x =

x⁴ =

x⁴ = 7

Therefore, Option (4) will be the answer.

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
