Answer:
x^4 - 81 = 0
(x² - 9)(x² + 9) = 0
Notice that the first of these is itself a difference of two squares:
(x - 3)(x + 3)(x² + 9) = 0
So the solutions are x = 3, x = -3, x = 3i, x = -3i
T= C(7+AB)
T = 7C + ABC
T - 7C = ABC
(T - 7C)/BC = A
If you are looking for an expression it would be x < 4 and the < has a line underneath for less than or equal to. If this is right could I possibly have brainliest? Hope this helped!! :)
Answer:
Step-by-step explanation:
2) Take the number you see (7). How many 7s are there? There are three.
7 x 3
3) What number do you see? 3. How many 3s? Five 3s.
3 x 5
Now you try
Step-by-step explanation:
Let assume that
We know,
So, using this, we get
Now, we use Method of Substitution, So we substitute
So, above expression can be rewritten as
So,
Thus,
<u>Hence, </u>
<u>Hence, Option (d) is </u><u>correct.</u>
