Use the product, quotient, and power rules of logarithms to rewrite the expression as a single logarithm. Assume that all variab
Viefleur [7K]

Answer:

log(x^7·y^2)

Step-by-step explanation:

The applicable rules are ...

... log(a^b) = b·log(a)

... log(ab) = log(a) +log(b)

_____

The first term, 7log(x) can be rewritten as log(x^7). Note that an exponentiation operator is needed when this is written as text.

The second term 2log(y) can be rewritten as log(y^2). These two rewrites make use of the first rule above.

Now, you have the sum ...

... log(x^7) +log(y^2)

The second rule tells you this can be rewritten as ...

... log(x^7·y^2) . . . . . seems to match the intent of the 3rd selection

Find the product of<br> (x2 + 3x + 1)(x2 + x + 2)
Bogdan [553]

Answer: x^4+4x^3+6x^2+7x+2

Step-by-step explanation:

To solve the exercise you must apply the following proccedure:

- Apply the distributive property.

- Keep on mind that when you multiply two powers with equal base, you must add the exponents.

- Add like terms.

Therefore, you obtain the following product:

=x^{(2+2)}+x^{(2+1)}+2x^2+3x^{(1+2)}+3x^{(1+1)}}+6x+x^{2}+x+2\\=x^4+x^3+2x^2+3x^3+3x^2+6x+x^2+x+2\\=x^4+4x^3+6x^2+7x+2

Ms.Ellis has a crate that is 5 feet tall, 6 feet wide, and 8 feet long. How many square feet of paint does she need to cover the
Vladimir [108]

Answer:

The answer to your question is 236 ft²

Step-by-step explanation:

Data

height = 5 ft

width = 6 ft

length = 8 ft

Area = ?

Process

I will consider that the crate is a rectangular prism which has 6 sides

1.- Find the area of the sides that measure 8 x 6

Area = 2 (8 x 6)

        = 2(48)

        = 96 ft²

2.- Find the area of the sides that measure 8 x 5

Area = 2(8 x 5)

Area = 2(40)

Area = 80 ft²

3.- Find the area of the sides that measure 6 x 5

Area = 2( 6 x 5)

Area = 2(30)

Area = 60

4.- Find the total area

Area = 96 + 80 + 60

Area = 236 ft²

5.- Conclusion

She needs 236 ft² of paint
