Solution: a (m+1+2n+1) * b (n+2+2m) = a 5 * b 3.
∴m+2n+2=5 ( 1)
2m+n+2=3 (2)
(2)-( 1) De: m-n=-2
2. If the m power of 5 =2 and the n power of 2 =4, find 2M-4+3 of 5.
This question is not clear, is it wrong?
3. The rational numbers x and y satisfy the absolute value of X+Y-5+square (x-y+ 1) =0. Find the square of (the square of xy) × (the square of x× the square of y).
∵|x+y-5| +(x-y+ 1)? =0
∴x+y=5
x-y=- 1
∴x=2,y=3
(the square of xy) the square of x (the square of x and the square of x y)
=(xy? )? *(x? *y? )?
=x? y^4*x^4*y^4
=x^6*y^8
When x=2 and y=3.
The original formula = 26 * 38 = 64 * 6561= 419904.
4\ From the meaning of the question: A=3
"3 A-3+2 3-A -B+300" equals?
5、3^(555)=(3^5)^ 1 1 1=243^ 1 1 1
4^(444)=(4^4)^ 1 1 1=256^ 1 1 1
5^(333)=(5^3)^ 1 1= 125^ 1 1 1
∵ 125 & lt; 243 & lt256
∴5^(333)<; 3^(555)<; 4^(444)
