<u>Answer:</u>
The coefficient of
<u>Solution:
</u>
The given expression is
As per binomial theorem, we know,
Now here a = 2x, b = (- 3y) and n = 10 and k = 0,1,2,….10
Now will be the 6 term where k =5
Now,
So, the coefficient of .
The coefficient of
Answer:
a=2, b=5
Step-by-step explanation:
Let
n -----> the denominator
we have
Solve for n
That means -----> isolate the variable n
Multiply by n both sides
Divide by 3.5*10^4 both sides
therefore
a=2, b=5
Answer:
12
Step-by-step explanation:
Answer:
-5,3
Step-by-step explanation:
Answer:
x = 75°
Step-by-step explanation:
Sum of the interior angles of a triangle = 180°
Therefore,
78° + 27° + x° = 180°
Add like terms
105 + x = 180
105 + x - 105 = 180 - 105 (substraction property of equality)
x = 75°
