Answer:
The given expression
after the negative exponents have been eliminated becomes 
Step-by-step explanation:
Given expression 
We have to write expression after the negative exponents have been eliminated and a ≠ 0 and b ≠ 0.
Consider the given expression
We have to eliminate the negative exponents,
Using property of exponents,
we have ,

Substitute, we get,
becomes 
Thus, the given expression
after the negative exponents have been eliminated becomes 
Let the base angle be x. If the obtuse angle is two and a half times the base angle, it will be 2.5x. In a triangle, all three angles will add up to 180. The third angle, the other base angle will be equal to x. So the equation will be:
x + x + 2.5x = 180
2x + 2.5x = 180
4.5x = 180
x = 40
If x = 40, then 2.5x = 100
