Can 171 19/32 be simplified

LenaWriter [7]

171 19/32=(171×32+19)/32=(odd number)/32.

But 32=2⁵

Thus, this ratio cannot be simplified, because the numerator is an odd number.

And the denominator is a power of 2.

PLEASE I REALLY NEED YOUR HELP!

Ivenika [448]

Answer:

x = 28

m∠ACD = 68°

Step-by-step explanation:

∠BAE ≅∠DAC because they are vertical angles

∠ACD = 180 - 124 = 56°

to find 'x': 56 + 2x + (180 - 4x) = 180

236 - 2x = 180

-2x = -56

x = 28

m∠ACD = 180 - 4(28) = 180 - 112 = 68°

Simplify the expression where possible.<br> (r ^-3 s^2 t) ^4

ASHA 777 [7]

$Use\\\\(ab)^n=a^nb^n\\\\ (a^n)^m=a^{n\cdot m}\\-------------------\\\\\left(r^{-3}s^2t\right)^4=\left(r^{-3}\right)^4\left(s^2\right)^4(t)^4=r^{(-3)(4)}s^{(2)(4)}t^4\\\\=\boxed{r^{-12}s^8t^4}\to\boxed{\dfrac{s^8t^4}{r^{12}}}$
