A) write √3×√6 in the form of b√2 where b is the insteger<br><br>b) simplify √8×√18<br>

Bas_tet [7]

Step-by-step explanation:

a.) the given term can be written as

$\sqrt{3} \times \sqrt{3 \times 2}$

$\sqrt{3 \times 3 \times 2}$

$3 \sqrt{2}$

hence the given term is

$3 \sqrt{2}$

where b = 3

b.)

$\sqrt{8} \times \sqrt{18}$

$\sqrt{2 \times 2 \times 2} \times \sqrt{2 \times 3 \times 3}$

$\sqrt{2 \times 2 \times 2 \times 2 \times 3 \times 3}$

$12$

hence the given term is 12

What binomial do you have to add to the polynomial 2x^2+3y^2-5xy+1 to get the following?

Contact [7]

Binomial $-3y^{2}+5xy$ when added to polynomial $2x^{2} +3y^{2} -5xy+1$ gives polynomial that does not contain the variable y .

<h3>What is binomial?</h3>

A mathematical expression consisting of two terms connected by a plus sign or minus sign .

Example: x + 2 is a binomial, where x and 2 are two separate terms.

<h3>What is polynomial?</h3>

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer

According to the question

polynomial $2x^{2} +3y^{2} -5xy+1$

when added with $-3y^{2}+5xy$

= $2x^{2}+1$ (as $3y^{2} -5xy$ got cancelled )

that does not contain the variable y

Hence, Binomial $-3y^{2}+5xy$ when added to polynomial $2x^{2} +3y^{2} -5xy+1$ gives that does not contain the variable y .
