Question

What is the following product?

4V7•4V7•4V7•4V7
A 4(4V7)
B 4v7
C 7^4
D 7

Answer 1

Option (4)

Explanation:

Let x =
`\sqrt[4]{7}`

`\sqrt[4]{7}* \sqrt[4]{7}* \sqrt[4]{7}* \sqrt[4]{7}` = (x)(x)(x)(x)

=
`x^(1+1+1+1)`

= x⁴

Now we substitute the value x =
`\sqrt[4]{7}`

x⁴ =
`(\sqrt[4]{7})^4`

x⁴ = 7

Therefore, Option (4) will be the answer.
