Answer:

The factorization of given expression $x^2 + 81$ is (x + 9i)(x – 9i) and option d is correct.

Solution:

Given, expression is $x^2 + 81$

We have to factor it in the complex numbers.

Let us check options to find answer.

A) (x – 9)(x – 9)

(x – 9)( x – 9) $=(x-9)^{2}=x^{2}-18 x+81$

So, this is not correct answer.

B) (x + 9)(x + 9)

$(x+9)(x+9)=(x+9)^{2}=x^{2}+18 x+81$

So, this is not correct answer.

C) (x + 9i)(x + 9i)

$(x+9 i)(x+9 i)=(x+9 i)^{2}=x^{2}+18 x i+81(-1)=x^{2}+18 x i-81$

So, this is not correct answer.

D) (x + 9i)(x - 9i)

$(x+9 i)(x-9 i)=x^{2}-(9 i)^{2}=x^{2}-(-81)=x^{2}+81$

Thus option D is correct

Hence, the factorization of given expression is (x + 9i)(x – 9i). and option d is correct.

Write 8xmxn without the multiplication sign

Katarina [22]

Step-by-step explanation:

$8mn$

or equivalently

$8\cdot m\cdot n$

We often write variable side-byside without the multiplication sign in algebra. It also applies to terms with indices. For instance,

$\text{We write }a^2b^3c^4\text{ and mean }a^2\times b^3\times c^4$

We may, often also add a dot at the middle of both terms as another version of multiplication sign for better readability if the terms are more complicated, for instance

$a\cdot b\cdot c$

and

$\frac ab\cdot \sqrt{\frac{d^4}{b^9}}\cdot\pi$
