Y = √ x-3 + 2 + √ x-3, then the value of XY is

Y = √ x-3 + 2 + √ x-3, then the value of XY is

y=√x-3 +2+ √x-3
In the range of real number, X can satisfy the independent variable only if it takes 3
y=2,
xy=6.

If (X-Y) ^ 2 = 2, xy = 3, then what is the value of (x + y) ^ 2

（x+y)²=(x-y)²+4xy
=4+12
=16

For a two digit number, the number on one digit is odd and composite, and the number on ten digit is even and prime. This number is ()
A. 24B. 42C. 29D. 92

For a two digit number, the number on the one digit is both odd and composite, and the number on the ten digit number is both even and prime. This number is 29

F (x) = 1 / [(3 ^ x) + 1] + A is the value of a for odd function

Because f (x) is an odd function, so f (0) = 0, substituting a = - 1 / 2

Second grade students fill in the numbers regularly

5000（5500 ）6000（ 6500 ）7000（ 7500 ）（ 8000）（ 8500 ）（ 9000 ）9500（ 10000）

If a natural number is used to remove another integer, the quotient is 28, the remainder is 10, and the sum of the divisor, divisor, quotient and remainder is 715, the divisor is______ The divisor is______ ．

The sum of divisor and divisor is: 715-28-10 = 677; divisor is: (677-10) / (28 + 1) = 667 / 29 = 23; divisor is: 23 × 28 + 10 = 644 + 10 = 654; so the answer is: 654, 23

If (k-1) x ^ 2 + KX + 8 = 0 is a linear equation of one variable with respect to x, then k =, X=

So k-1 = 0
k=1
x+8=0
x=-8
A: k = 1, x = - 8

If a natural number is multiplied by two adjacent even numbers, the difference of the product is 18______ ．

Because the difference between two adjacent even numbers is 2, the number is: 18 △ 2 = 9; answer: the number is 9, so the answer is: 9

Root of the third power 4 * root of the fourth power 8 / root of the third power 16 * root of the sixth power 32

(&# 179; √ 4 * &# 8308; √ 8) / (√ 16 * (6 times) √ 32)
=[2^(2/3)*2^(3/4)]/[2^4*2^(5/6)]
=2^(2/3+3/4-4-5/6)
=2^(-41/12)
