Answer:

<h2>Check the explanation.</h2>

Step-by-step explanation:

The highest four digit number is 9999 and lowest 4 digit number is 1000. The difference between them is (9999 - 1000) = 8999.

8999 cannot be difference according to the question, as here all the digits should be distinct rather than 0.

The difference between the 9 and 1 is 8, which is the highest difference among the unit digits rather than 0.

The 2nd lowest number after 9 is 8 and the 2nd highest unit digit after 1 is 2.

(8 - 2) = 6.

The difference will be highest if difference is calculated between the highest and lowest number.

With the 4 digits, 9, 8, 2, 1 the lowest number is 1289 and the highest number is 9821.

The difference is (9821 - 1289) = 8532.

Trava [24]

Answer:

a=22,\\b=31,\\c=13

Step-by-step explanation:

When choosing equations to write, make sure you choose a pair that allow you to isolate a variable and solve for it.

Sample solution:

a+25+28=16+25+34,\\\\a+28=16+34,\\a+28=50,\\a=\boxed{22}

16+b+28=16+25+34,\\b+44=75,\\b=\boxed{31}

34+c+28=16+25+34,\\c+28=41,\\c=\boxed{13}

Answer:

  6.5e^(i·(-157.38°)) ≈ 6.5e^(-2.7468i)

Step-by-step explanation:

A suitable calculator can find the value of this ratio for you.

  ((2+3i)/(1-i))² = -6 -2.5i ≈ 6.5∠-157.38° ≈ 6.5e^(-2.7468i)
