How is this written in an expanded version?
Yuri [45]

Powers distribute over multiplications:

(ab)^c = a^c\cdot b^c

So, you have

(3k^5)^2 = 3^2 \cdot (k^5)^2

Now, 3^2 is simply 9.

As for (k^5)^2, we have to use the rule

(a^b)^c = a^{bc}

to get

(k^5)^2=k^{5\cdot 2}=k^{10}

So, the final answer is

(3k^5)^2 =9k^{10}

Write the equation of the line that passes through (2,7) and (0, 1).
dsp73

Answer:

y=3x+1

Step-by-step explanation:

First, you need to find the slope. With the two points you can find the slope by subtracting one point from the other. This gives you a slope of 3. You could plot this on a graph to get the +1, or you can just look at these two points. (0,1) just gives it to you because this point is on the line.

A floor 10m by 40m is covered by square tiles 20cm. How many tiles are needed to cover the floor?
Lady_Fox [76]

Answer:

10,000

Step-by-step explanation:

We can find the area of the floor in cm^2 and divide by the are of 1 tile in cm^2.

1 m = 100 cm

10 m = 1000 cm

40 m = 4000 cm

area of floor = LW = 1000 cm * 4000 cm = 4,000,000 cm^2

area of tile = s^2 = (20 cm)^2 = 400 cm^2

number of tiles = 4,000,000/400 = 10,000

Answer: 10,000 tiles
