Adding and subtracting the given polynomials

Usimov [2.4K]

You have to combine like terms, so the variable (x, y, s, d, c....) and the exponents must be the same in order to combine them.

For example:

x² + x³ Since they don't have the same exponent, you can't combine them

y² + 3y² = 4y²

23x + x = 24x

4. 2s² + 1 + s² - 2s + 1 You can rearrange it if it makes it easier

2s² + s² - 2s + 1 + 1 = 3s² - 2s + 2

5. 5t² - 2t - 1 - (3t² - 5t + 7) Distribute/multiply the - to (3t² - 5t + 7)

5t² - 2t - 1 - 3t² + 5t - 7 = 2t² + 3t - 8

Do the same for #9 and #10, and you should get:

9. 2k² + 5k - 9

10. 6y³ - 7y² - 6y - 12

What is the value of log(x exponent 2 y exponent 3 divided by z) when given the following:

Gekata [30.6K]

Answer:

B. 13

Explanation:

$\sf\:Given\:expression: log(\dfrac{x^2 y^3}{z} )$

Logarithm rules:

$\sf (i) \ \sf log(ab) = log(a) + log(b)\\ \\ (ii) \ log(a/b) = log(a) - log(b)\\\\ (iii) \ log(a^n) = n log(a)$

Breakdown of the expression:

$\rightarrow \sf log\left(\dfrac{x^2y^3}{z}\right)$

$\rightarrow \sf log\left(x^2\right) + log\left(y^3\right) - log(z)$

$\rightarrow \sf 2\log\left(x\right)+3\log \left(y\right)-\log \left(z\right)$

insert given values

$\rightarrow \sf 2(3)+3(2)-(-1)$

$\rightarrow \sf 13$

(3a^4b)(5ab^2)-(a^5b^2)(9b)

Sliva [168]

Answer:

The expanded value of the given expression is

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=6a^5b^3$

Step-by-step explanation:

Given expression is

$(3a^4b)(5ab^2)-(a^5b^2)(9b)$

To find the value of the given expression:

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=15a^5b^3-9a^5b^3$

(By multiplying the products and doing algebraci subtracion of the above expression)

Now taking the common terms in the above equation we get

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=3a^5b^3(5-3)$

$=3a^5b^3(2)$

$=6a^5b^3$

Therefore the expanded value of the given expression is

$(3a^4b)(5ab^2)-(a^5b^2)(9b)=6a^5b^3$
