Question

Which value of x makes the expression above equivalent to 14 Square root 7?

Pls helppppppppppppppp

Answer 1

B. 4

Explanation:

• First, let's evaluate the first expression:

`7 √(7x) = √(49 * 7x)`

• We can just remove the √ from both sides to make it easier to see, so

49 × 7x = 343x

• Now, let's evaluate the second expression:

14√7 = √(1372)

• To see what value would make the first expression equal to the second expression, we can divide the the second expression by first expression:

1372 ÷ 343 = 4 this is the vaule of x.
