Simplify.Your answer should contain only positive exponents.

zhannawk [14.2K]

Step-by-step explanation:

1) $r^3r^3$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}$

$=r^{3+3}$

$=r^6$

2) $3k^3k^3$

$\mathrm{Apply\:exponent\:rule}:\quad \:a^b\cdot \:a^c=a^{b+c}$

$=3k^{3+3}$

$=3k^6$

3) $\left(3b^2\right)^3$

$\mathrm{Apply\:exponent\:rule}:\quad \left(a\cdot \:b\right)^n=a^nb^n$

$=3^3\left(b^2\right)^3$

$=27\left(b^2\right)^3$

$=27b^6$

4) $\left(2m^3\right)^3$

$\mathrm{Apply\:exponent\:rule}:\quad \left(a\cdot \:b\right)^n=a^nb^n$

$=2^3\left(m^3\right)^3$

$=8\left(m^3\right)^3$

$=8m^{3\cdot \:3}$

$=8m^9$

5) $\frac{3r^3}{r^2}$

$\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}$

$=3r^{3-2}$

$=3r^1$

$=3r$

IM GIVING 20 POINTS. Help me with this please. it would be very helpful.

Talja [164]

Solution:

hypotenuse=p

perpendicular=m

base=n

According to Pythagoras theorem,

h^2=p^2+b^2

So the right answer of your question is m^2+n^2=p^2

Right answer is of option A.

Hope it helps....

Good luck on your assignment

Rufina [12.5K]

In my understanding, the component form of a vector is the ordered pair that describes the changes in the x- and y-values.

Therefore to get it
you must add all the
x
(0 + (-6) + (-6) + 6)
= -6

Then add all y
(7 + 7 + (-11) + (-11)
= -8

Answer = (-6,-8)

Identify the domain of the exponential function shown in the following graph :

Vinil7 [7]

Answer:

The domain of this exponential function is (all real numbers).

Step-by-step explanation:

The domain is all real numbers because according to the x-axis the function passes through all numbers the negative and positive. As you see the graph is continuous which means it will keep on going.

I hope this helps!
