Here's how you simplify those. The rule for raising an exponent to an exponent is that you multiply them. The rule for dividing exponents with the same base is that you subtract the denomonator from the numerator.  So let's simplify the first one, which is actually the most confusing.
( \frac{ p^{5} }{ p^{-3} q^{-4}  } )^{ \frac{1}{4} }
Multiplying the exponents you get:
( \frac{ p^{ \frac{5}{4} } }{ p^{- \frac{3}{4} }  q^{-1} })
Subtracting the denominator from the numerator between the common base of p you get this:
\frac{ p^{ \frac{5}{4}- (-\frac{3}{4})  } }{ q^{-1} }
Doing that math gives you
\frac{ p^{2} }{ \frac{1}{q} } which equals \frac{ p^{2} }{1} * \frac{q}{1} which is p^{2}q, or the third one down.

The next one:
( \frac{ p^{2} q^{7}  }{ q^{4} } )^{ \frac{1}{2} }
simplifies to:
\frac{p* q^{ \frac{7}{2} } }{ q^{2} }
and subtracting the power of the denominator from the power of the numerator gives you:
p q^{ \frac{3}{2} }, which is the last choice.
( p^{6}q \frac{3}{2})^{ \frac{1}{3} }
simplifies to:
( p^{6* \frac{1}{3} } )( q^{ \frac{3}{2}* \frac{1}{3}  })
which simplifies very nicely to:
p^{2}q^{ \frac{1}{2} }, which is the first choice. The other one is found by process of elimination!

In triangle ABC, the right angle is at vertex C, a = 714 cm and the measure of angle A is 78° . To the nearest cm, what is the l
rewona [7]

Answer:

c = 730cm

Step-by-step explanation:

The first thing we would do is to draw the diagram using th given information.

Find attached the diagram.

a = 714 cm

the measure of angle A = 78°

To determine c, we would apply sine rule. This is because we know the opposite and we are to determine the hypotenuse

sin78 = opposite/hypotenuse

sin 78 = 714/c

c = 714/sin 78 = 714/0.9781

c= 729.99

c≅ 730 cm ( nearest cm)
