Answer:
<u>x² + 8x + 16</u>
Step-by-step explanation:
You can draft the Pascal's Triangle as below;
Exponent
1-----------------------0
1 1 -------------------1
1 2 1 ------------------2
1 3 3 1 -----------------3
According to the question, we use values for exponent 2 because (a+b)²
Given (x+4)²...................................expand
x² × 4⁰ + x¹ × 4¹+ x⁰ × 4²
x² × 1 + x × 4 + 1 × 16
x² + 4x + 16---------------------------------introduce values in exponential 2 of the table which are 1 2 1
x² × 1 + 2 × 4x + 16 × 1
⇒ <u>x² + 8x + 16</u>
Answer:
Option A is correct.
The given expression : then;
Step-by-step explanation:
Given the expression:
Cross multiplication the given expression following steps are as follow;
- Multiply numerator of the left-hand fraction by the denominator of the right-hand fraction
- Also, Multiply numerator of the right-hand fraction by the denominator of the left-hand fraction.
- then, set the two products equal to each other.
Using cross multiplication, on the given expression;
First multiply the numerator of the left hand fraction(i.e,a ) by the denominator of the right hand fraction (i,e a)
we have;
Simplify:
[1]
now, multiply numerator of the right-hand fraction( i.e, 9) by the denominator of the left-hand fraction (i.e, 4 ) in [1]
we have;
Simplify:
Therefore, the given expression is equal to:
The 17th term is 50C16*2^34*a^16
The 18th term is 50C17*2^33*a^17
The ratio of these two terms is (17th term)/(18th term) = 1/a. We want the value of this to be 1, so
.. A = 1
_____
My calculator says
.. 50C16 = 4,923,689,695,575
.. 50C17 = 9,847,379,391,150
the latter being exactly 2 times the former.
