Answer: -1
Raising one exponential expression to another exponent means you multiply the exponents together. We have 5*5 = 25 as the new exponent.
So we end up with (-1)^25 = -1
The rule I'm using is that -1 to any odd whole number power is going to result in -1. If the exponent was even, then -1 to that power would be 1.
So in short, the rule says
(-1)^n = -1 if n is an odd whole number
(-1)^n = 1 if n is an even whole number
Answer:
6/5
Step-by-step explanation:
When two lines are perpendicular to each other, their slope are the negative reciprocal to each other. (so you flip them and change the sign)

Answer:
More than one triangle can be formed by three angles measuring 75°, 45° and 60°. Solution : We know that, The sum of the measures of all angles of a triangle should be equal to 180
Step-by-step explanation:
The sqrt(7) part makes it irrational, so the answer is irrational.
