A) x^5/6 ≠ 5√6, Because 5 is in numerator & 6 in denominator in exponential expression so it can be in direct expression.

It is False.

b) (16)^1/4 = 2.
It is False

c) a^2/7 + a^4/7 = a^2/7+4/7 = a^6/7
It is False.

d) Here, powers are not equivalent.
Again, It is False

e) (27x^6)^2/3 = 27^2/3 x^12/3
 = 9x^4
It is True.

13) Here, expression would be: a^2/3
In short, Your Answer is Option B

14) ∛8x^6
= ∛8 x^6/3
= 2x²
In short, Your Answer would be Option C

Hope this helps!

What are the sine cosine and tangent of theta=7pi/4 radians
FrozenT [24]

Answer:

see explanation

Step-by-step explanation:

\frac{7\pi }{4} is in the fourth quadrant

Where sin and tan are < 0 , cos > 0

The related acute angle is 2π - \frac{7\pi }{4} = \frac{\pi }{4}

Hence

sin([\frac{7\pi }{4} ) = - sin(\frac{\pi }{4}) = - \frac{1}{\sqrt{2} } = - \frac{\sqrt{2} }{2}

cos(\frac{7\pi }{4}) = cos(\frac{\pi }{4}) =  \frac{\sqrt{2} }{2}

tan(\frac{7\pi }{4}= - tan(\frac{\pi }{4} = - 1
