Answer:
Step-by-step explanation:
Given
Required
Find
In trigonometry:
This gives:
So:
This gives:
X^4=256
x^4-256=0
(x^2)^2-(16)^2=0
(x^2+16)(x^2-16)=0
either x^2+16=0
it gives complex roots.
or x^2-16=0
or x^2-4^2=0
(x+4)(x-4)=0
either x+4=0,x=-4
or x-4=0
x=4
Answer:
=(a-b)(a^2+ab+b^2)
= a^3+a^2b+ab+ab^2-ba^2-ab^2-b^3
SIMPLIFY
=a^3+ab-b^3
Answer:
D x>-3
Step-by-step explanation:
3(-x+2) < 15
-3x + 6< 15 (Subtract 6 from both sides)
-3x < 9 (Divide 3 on both sides)
x>-3 (Flip the inequality because the variable was negative)
