1. N= 16 because like the base are equal so you have to multiply the 8*2

2.N=16 because like the bases are identical but the 2*8 they multiply

Answer:

n = 10 and n = 16

Step-by-step explanation:

Using the rules of exponents

[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , then

[tex]4^{8}[/tex] × 4² = [tex]4^{(8+2)}[/tex]

= [tex]4^{10}[/tex] , thus n = 10

---------------------------------------------

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , then

[tex](3^2)^{8}[/tex]

= [tex]3^{2(8)}[/tex]

= [tex]3^{16}[/tex] , thus n = 16

A submarine starts at 0 units and has groups of 3 floats and groups of 4 anchors attached.
Using these groups of floats and anchors, write as many different expressions as you can that would make the submarine's final position -5 units.
write three expressions

Answers

Answer:

-12

Step-by-step explanation:

The three equivalent expressions of the final position are:

-(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)

From the question,

Each float takes a step of 5 unitsEach group takes a step of 2 units

So, the final position of the submarine is:

Final = -(5)(3) - (2)(4)

The minus "-" sign implies that the submarine moves downwards i.e. it sinks

The equivalent expressions of the final position are:

-(5)(3) - (2)(4), -(5)(3) + (-2)(4) and -(5)(3) + (2)(-4)

1 floor per 13 feet.

It means how many floors are to be allocated in a certain area of space.

Step-by-step explanation:

Answer:


Meaning: Each floor of the buiding has a height of 15 feet.
Step-by-step explanation:
The missing figure is attached.
By definition, the ratios are used to compare two or more things or quantities.
In this case you must write the ratio of height of the building to the number of floors it has.
You can observe in the figure that the building has a height of 135 feet, and, since it has 9 floors, you can write the following ratio:

Therefore, dividing the numerator by the denominator, you get that the unit rate is:

This means that each floor of the buiding has a height of 15 feet
