a. B is opposite to each other, the product of C and D is - 1, and the absolute value of X is 4 Eighth x square C third power D third power - fifteenth x third power (a + b) fifth power

a. B is opposite to each other, the product of C and D is - 1, and the absolute value of X is 4 Eighth x square C third power D third power - fifteenth x third power (a + b) fifth power

∵ A and B are opposite numbers, the product of C and D is - 1, the absolute value of X is 4 ∵ a + B = 0, C · d = - 1, x = ± 4 ∵ one eighth x square, C cubic power, D cubic power - one fifteenth X Cubic power (a + b) quintic power = (1 / 8) (- 4) & ∵ 178; × (- 1) & ∵ 179; - (1 / 15) × (- 4

Fill - 1 + 2-3 + 4-5 + 6-7 + 8-9 in the box of 3 times 3, so that the sum of the absolute values of the three numbers on each diagonal of each row and column is equal

6,-7,2
-1,-5,-9
8,-3,4

It is known that the absolute value of a divided by a plus B plus C is equal to 1. Find the absolute value of ABC divided by ABC
Divided by (absolute value of AC divided by BC multiplied by absolute value of BC divided by AC multiplied by absolute value of AC divided by ab)

[a/|a|]＋[|b|/b]＋[|c|/c]=1
Then: if there are and only two numbers in a, B and C are positive and the other number is negative, then:
abc

Given that a and 2b are reciprocal to each other, - C and 2 / D are opposite to each other, x = 4, find the value of 4ab-2c + D + 4 / X

A = 1 / 2
-C = - C / 2
x=4
4ab-2c = D = 4 / 4 x = 8
