QUICKKK?!!

Tju [1.3M]

Step-by-step explanation:

the line passing through the points (-7, - 7) and (4,-7).

Slope: (-7+7) /(4+7) = 0/11 = 0

this is a horizontal line

through the points (4,7) and (4, -6).

slope: (-6-7) /(4-4) = -13/0 = oo

this is a vertical line

When x = 2e, <img src="https://tex.z-dn.net/?f=%5Clim_%7Bh%20%5Cto%200%7D%20%5Cfrac%7Bln%28x%20%2B%20h%29%20-%20ln%28x%29%7D%7Bh

dybincka [34]

Supposing you know about the derivative, notice that

$\displaystyle\lim_{h\to0}\frac{\ln(x+h)-\ln x}h=\dfrac{\mathrm d(\ln x)}{\mathrm dx}=\dfrac1x$

so that when $x=2e$ , the limit is equal to $\dfrac1{2e}$ and the answer is A.

What is the value of (9^7) ^3/14, in simplest terms? a0

s2008m [1.1K]

Answer:

27.

Step-by-step explanation:

It is one property of exponents that for any numbers a, b, and c

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

Therefore, using this property the expression $(9^7) ^{3/14}$ becomes

$(9^7) ^{3/14} =9^{(7*\frac{3}{14} )}$ .

and when when simplify the exponents, we get:

$9^{(\frac{21}{14} )}= 9^{\frac{3}{2} }= (9^{\frac{1}{2} })^3$ .

Since for any number $a^\frac{1}{2} =\sqrt{a}$ ( $\dfrac{1}{2}$ in the exponent means the square root) , $(9^{\frac{1}{2} })^3$ is rewritten as

$(\sqrt9} )^3$

which simplifies to

$(\sqrt9} )^3=3^3 =\bold{27}$

Thus,

$\boxed{ (9^7) ^{3/14}=27}$
