Answer:

$3^2$

Step-by-step explanation:

$\frac{3^8*\:3^4}{3^2*\:3^8}$

Apply Exponent rule: $a^b\cdot \:a^c=a^{b+c}$

$\frac{3^{12}}{3^8* \:3^2}$

$\frac{3^{12}}{3^{10}}$

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

$3^{12-10}=3^2$

PLEASE ANSWER PROPERLY The law of cosines is used to find the measure of Z.

gladu [14]

16² = 18² + 19² - 2(18)(19)cos(z)

256 = 324 + 361 - (684)cos(z)

256 = 685 - (684)cos(z)

-429 = -684cos(z)

cos(z) = -429/-684

z = cos⁻¹ (0.627)

z = cos⁻¹ (cos 51) [ Cos 51 = 0.627 ]

z = 51

In short, Your Answer would be: 51

Hope this helps!
