Question

18*=?

Answer 1

$18\cdot \frac{\sqrt3}{2}=\frac{2\cdot 9\cdot \sqrt3}{2}=9\sqrt3$

Answer 2

$18 \times \frac{ \sqrt{3} }{2} =9 \sqrt{3}$

Answer 3

The expression "18*=?" is incomplete and cannot be evaluated as is. In mathematical terms, the "" symbol represents multiplication, but there is no value or variable after the "", so it's not possible to provide a numerical answer.

If you provide the missing number or variable, I'd be happy to help you solve the equation! For example, if you meant "18 * x = ?", then I can help you solve for the value of "x."
