For this case we have:
By definition, one of the properties of the power, known as negative integer power, states that:
can be written as
Thus, can be written as
. So:
Answer:
Power of negative integer exponent:
Can someone help me solve this problems
1 answer:
x = 4 and x = - 9
In both cases the angles inside the parallel lines are same sided interior angles
24x - 1 + 20x + 5 = 180
44x + 4 = 180 (subtract 4 from both sides )
44x = 176 ( divide both sides by 44 )
x = = 4
Similarly
x + 109 + x + 89 = 180
2x + 198 = 180 ( subtract 198 from both sides )
2x = - 18
x = = - 9
