Your answer was wrong. You flip 3/4 to 4/3
1/2 ÷3/4 =
1/2 ×4/3 = 4/6
4/6 ÷2 = 2/3 is the answer

X is -4<br><br> f(x)= 5x^8-3x<br><br><br> The ^8 is the exponent for 5x!!!

Answer:

327692

Step-by-step explanation:

$65536 = (-4)^{8} \\ \\ 65536 \times 5 = 327680 \\ \\ 327680 - 3(-4) = 327680 + 12 = 327692$

According to the Order of Operations [GEMS(A)\BOMDAS\PEMDAS etc.], in this case, you evaluate the exponent BEFORE multiplying. This is a <em>common</em><em> </em><em>mistake</em><em> </em>people make.

zaharov [31]

Answer:

see explanation

Step-by-step explanation:

Co terminal angles are angle ± 2π, that is

$\frac{11\pi }{8}$ + 2π

= $\frac{11\pi }{8}$ + $\frac{16\pi }{8}$ = $\frac{27\pi }{8}$

and

$\frac{11\pi }{8}$ - 2π

= $\frac{11\pi }{8}$ - $\frac{16\pi }{8}$ = - $\frac{5\pi }{8}$
