I'm helping my son with his algebra (attempting to anyway). We've got a problem that I can't quite understand... Simplify the equation (3x^-3)^2(-2xy). I

Answers

Answer 1

Answer: $(3x^(-3))^2(-2xy)}$

The square (²) can be distributed to each factor inside those parentheses.
3² = 3 × 3 = 9
as for the x^-3, we want to multiply our exponents together, leaving x^-6.

$(9x^(-6))(-2xy)$

Note that since multiplication is commutative/associative, we can multiply these together in whatever order to simplify.

The x on the right can be rewritten as x¹. Multiply that and x^-6 together to get x^-5. (we just add the exponents)
As for the 9 and -2, multiply those together to get -18.

Now we have $-18x^(-5)y$ .

Lastly, if you don't want a negative exponent in your answer:
It can be flipped to the bottom because of this property:

$x^(-n)=(1)/(x^n)$

This leaves us with $\boxed{(-18y)/(x^5)}$

How do you conjugate verbs in the preterit?I need a really good explanation and can you include different verbs like ar, ir, and er?

Answers

To conjugate verbs in the preterite tense you just have to remove the infinitive endings and add the correct preterit ending depending on who the subjects of the action is. You already know the different verb endings ar ir and er. ir and er verbs have the same preterite endings
The different subjects are
1.yo
2. tú
3.usted, él, ella
4. nosotros
5. vosotros
6. ustedes, ellos, ellas

For ar verbs yo would drop the ar and add the ending accordingly so for
1. Yo the ending would change to -é
2. tú the ending would change to -aste
3. usted, él, ella the ending would change to -ó
4. nosotros the ending would change to -amos
5. vosotros the ending would change to -asteis
6. ustedes, ellos, ella, the ending would change to -aron

For the ir and er verbs, you would drop the ir or er and add
1. Yo the ending would change to -í
2. tú the ending would change to -iste
3. usted, él, ella the ending would change to -ió
4. nosotros the ending woul change to - imos
5. vosotros the ending would change to -isteis
6. ustedes, ellos, ellas the ending would change to -ieron

An example would be an ar verb viajar
1. Yo viajé
2. Tú viajaste
3. Él (ella, ud.) viajó
4. Nosotros viajamos
5. Vosotros viajasteis
6. Ellos (ellas, uds.) viajaron
