\frac{(5 \:  -  \: 8x)}{( \sqrt{5 \:  -  \: 8x} )}  \:  =  \:  \sqrt{5 \:  -  \: 8x}
For the result to be Real,
5 \:  -  \: 8x \:  \geqslant  \: 0
8x \:  \leqslant  \: 5
x \:  \leqslant  \:  \frac{5}{8}
( \frac{(5 - 8x)}{( \sqrt{5 - 8x} )} ) \:  \times  \:  (\frac{ \sqrt{5 - 8x} }{ \sqrt{5 - 8x} } ) \:  =  \:  \frac{ {(5 \:  -  \: 8x)}^{ \frac{3}{2} } }{(5 \:  -  \: 8x)}
Hence,
\frac{{(5 \:  -  \: 8x)}^{ \frac{3}{2} } }{(5 \:  -  \: 8x)}
is the required form.

Find the sum of the reciprocals of two consecutive even integers if the larger integer is x. please answer;-;​
Harman [31]

Step-by-step explanation:

Let the larger integer be x

Hence, the smaller integer = x-2

Hence,

Reciprocal of the x= 1/x

Reciprocal of x-2= 1/ x-2

Hence. their sum=

\frac{1}{x}  +  \frac{1}{x  - 2}  \\  =  \frac{x - 2 + x}{x(x - 2)} \\  =  \frac{2x - 2}{ {x}^{2}  - 2x}

Which expression is equivalent to -9x^-1y^-1 / -15x^5 y^-3 Assume x = 0 y = 0
jenyasd209 [6]
For this case we have the following expression:
   -9x ^ -1y ^ -1 / -15x ^ 5 y ^ -3
 For power properties we have:
   -9x ^ (- 1-5) y ^ (- 1 - (- 3)) / - 15
 Rewriting we have:
   9x ^ (- 6) y ^ (- 1 + 3) / 15
   3x ^ (- 6) y ^ (2) / 5
   3y ^ 2 / 5x ^ 6
 Answer:
 
  3y ^ 2 / 5x ^ 6Note: answer is not between the options. Rewrite the expression again, or the options.
