Question

-5 *√3/2 * 1/2 - 1/2 * √3/2=

Answer 1

-5 *√3/2 * 1/2 - 1/2 * √3/2 = -5√3/4-√3/4 = -3√3 /2

Answer 2

To calculate the expression, let's break it down step by step:

-5 * √3/2 * 1/2 = -5 * (√3/2) * (1/2) = -5 * √3/4

-1/2 * √3/2 = (-1/2) * (√3/2) = -√3/4

Now, we can subtract the two results:

(-5 * √3/4) - (√3/4) = -5 * √3/4 - √3/4 = (-5 - 1) * √3/4 = -6 * √3/4

Thus, the simplified result is -6 * √3/4.
