To evaluate the expression " _²30° - tan²30° = 1", we can use the identity _²30° = 1 / tan²30°. Substituting this identity into the given expression, we get:
1 / tan²30° - tan²30° = 1
Simplifying this further, we get:
tan²30° - tan²30° = 1
Which simplifies to:
0 = 1
This expression is not true, so the given expression is not correct.
