What is the solution for t in the equation 3 x √(t) = 39?

To find the solution for ( t ) in the equation ( 3 \times \sqrt{t} = 39 ), we start by isolating ( \sqrt{t} ). Dividing both sides of the equation by 3 gives us ( \sqrt{t} = \frac{39}{3} ), which simplifies to ( \sqrt{t} = 13 ).

Next, to eliminate the square root, we square both sides of the equation:

[

(\sqrt{t})^2 = 13^2

]

This results in ( t = 169 ).

Thus, the correct answer is 169, which accurately represents the solution for ( t ). This answer reflects the proper manipulation of the equation to isolate the variable and solve for it.
