square root of(0.0169 x ?) = 1.3

  1. 10

  2. 100

  3. 1000

  4. none of these


Correct Option: B
Explanation:

To solve this question, the user needs to know how to solve equations involving square roots and basic arithmetic. The user must also understand that the square root of a product is equal to the product of the square roots.

We start by isolating the variable in the equation:

$$\sqrt{0.0169x} = 1.3$$

We can then solve for x by squaring both sides of the equation:

$$0.0169x = 1.69$$

$$x = \frac{1.69}{0.0169} = 100$$

Therefore, the answer is option B: 100, since it is the only value that satisfies the equation.

Option A and C are incorrect since they are not the correct value of x that satisfies the equation. Option D is also incorrect since we have found a value of x that satisfies the equation, which is 100.
