90^6=531441000000
80^-4= 1/80^4= 1/4960000
For this, use negative power rule x^-a= 1/x^a
Answer:
a=b
Step-by-step explanation:
When the denominator is zero, the expression is undefined
a-b=0
a=b
Its going to be (8/15) and (12/5)
Answer:
B
Step-by-step explanation:
T(x)=3x³-2x²-6x-5
T(2)=3(2)³-2(2)²-6(2)-5
=24-8-12-5∵
=-1
Solution:
The given statement is :Two supplementary angles are congruent.
Two angles are said to be supplementary if sum of these two angles is 180°.
Let one Angle be A, then another angle will be 180 - A.
As given:
A≅180-A
A=180 -A
A +A= 180
2 A = 180
Dividing both sides by 2, we get
A= 90°
The Measure of each angle will be of 90°.
i.e , d = 90°
