Expandir (x + 2y)^5

Mathematics
1 answer:
GrogVix [38]3 years ago
8 0
This is the concept of polynomial function, the question requires us to compute;
(x+2y)^5
=(x+2y)^2(x+2y)^2(x+2y)
=[(x^2+4xy+4y^2)(x^2+4xy+4y^2)](x+2y)
=[x^2(x^2+4xy+4y^2)++4xy(x^2+4xy+4y^2)+4y^2(x^2+4xy+4y^2)](x+2y)
=(x^4+8x^3y+24x^2y^2+32xy^3+16y^4)(x+2y)
=x(x^4+8x^3y+24x^2y^2+32xy^3+16y^4)+2y(x^4+8x^3y+24x^2y^2+32xy^3+16y^4)
=x^5+10x^4y+40x^3y^2+80x^3y^3+80xy^4+32y^5
the answer is:
=x^5+10x^4y+40x^3y^2+80x^3y^3+80xy^4+32y^5

If 3x+54+(65 × 32)+ 902- (43/12) =y, then what is y?
IceJOKER [234]

Answer:

We cannot solve without a value for x. The simplified form is 3x+\frac{36,389}{12} =y

Step-by-step explanation:

If the equation is 3x+54+(65)(32)+902-\frac{43}{12}=y then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.

3x+54+(65)(32)+902-\frac{43}{12}=y \\3x+54+2,080+902-\frac{43}{12}=y \\3x+3,036-\frac{43}{12}=y \\3x+\frac{36,432}{12} -\frac{43}{12} =y\\3x+\frac{36,389}{12} =y

Determine the quotient: (22.8 × 10–3) ÷ (5.7 × 10–6)
lana66690 [7]

Answer:

0.399

Step-by-step explanation:

The key to doing this problem properly lies in knowing and following order of operations rules.

Here we must perform mult. and div.  before  addition and subtr., but even before that we must do all work enclosed in parentheses first.

(22.8 × 10–3) is evaluated by doing the mult. first, and then subtracting 3:

(228-3) = 225

and

(5.7 × 10–6) is evaluated by doing the mult. first, then subtracting 6:

(570-6) = 564.

Finally, we divide 225 by 564, obtaining 0.399 (after rounding off to three decimal places).
