Answer:

The number is 37

Step-by-step explanation:

The given parameters are;

The unit digit of a two-digit number = 4 + The tens digit

2 × The two-digit number  = 1  + The reversed number

Let x represent the unit digit and y represent the tens digit, we have;

x = 4 + y

2 × yx = xy + 1

Which gives;

2 × yy+4 = 2y2y+8

xy + 1 = 4 + yy + 1

y + 1 = 2y + 8 - 10 (we assume that the product of 2 and the unit digit is more than 10 so we subtract 10 from the product to equate the unit digits of the two numbers

10 + 1 - 8 = 2y - y

10 - 7 = y

y = 3

x = y + 4 = 3 + 4 = 7

x = 7

Therefore, the number = 37.

Reduce the following rational expression to the lowest form
snow_tiger [21]

Answer:

4x(x - 1)

Step-by-step explanation:

Factor the numerator and denominator

64x^{5} - 64x ← factor out 64x from both terms

= 64x(x^{4} - 1) ← difference of squares

= 64x(x² - 1)(x² + 1) ← x² - 1 is also a difference of squares

= 64x(x - 1)(x + 1)(x² + 1)

---------------------------------

(8x² + 8)(2x + 2) ← factor out 8 and 2 from each factor

= 8(x² + 1) × 2(x + 1)

= 16(x² + 1)(x + 1)

Then expression can be written as

\frac{64x(x-1)(x+1)(x^2+1)}{16(x^2+1)(x+1)} ← cancel (x² + 1) and (x + 1) on numerator/ denominator

= \frac{64x(x-1)}{16} ← cancel common factor 16 on numerator/ denominator

= 4x(x - 1)
