Question

Simplify the radical expression that does NOT simplify to 10.

Answer 1

A.

• Option A

√10 ≈ 3

2 × 3 ≈ 6

• Option B

√25 = 5

√4 = 2

5 × 2 = 10

• Option C

`(300)/(3)=100\\√(100)\\100=10^2\\√(10^2)\\√(10^2)=10`

• Option D

`1000=10^3\\\sqrt[3]{10^3}\\\sqrt[3]{10^3}=10(\mathrm{Radical\:rule)}\\`

Thus,

option A. is correct.
