Calculate the 2n + 1 power of the 2nd power * (- XY) of [3 (- XY) to the nth power] (n is a positive integer)

Calculate the 2n + 1 power of the 2nd power * (- XY) of [3 (- XY) to the nth power] (n is a positive integer)

[3(-xy)^n]^2*(-xy)^(2n+1)
=9(-xy)^2n*(-xy)^(2n+1)
=9(-xy)^(2n+2n+1)
=9(-xy)^(4n+1)
=-9(xy)^(4n+1)

Given that 2n power of x = 2, 4N power of y = 3, find 8N power of [XY]. Question 2: if 2x + 5Y = 3, find x power of 4 times y power of 32
Solve it@@

x^2n=2
y^4n=3
(xy)^8n
=x^8n*y^8n
=(x^2n)^4*(y^4n)^2
=2^4*3^2
=16*9
=144
4^x*32^y
=(2^2)^x*(2^5)^y
=2^2x*2^5y
=2^(2x+5y)
=2^3
=8

Given 2x-3y = 2, what is the 2x power of 3 divided by the XY power of 3?

It's a mistake. It's the 3Y power of 3
2X power of 3 divided by 3Y power of 3
=2x-3y power of 3
=3²
=9

Calculation: 2n + 2 power of (x + y) / [1 / 2 (x + y) n + 1 power]

: 2n + 2 power of (x + y) / [1 / 2 (x + y) n + 1 power]
=(1÷1/2)×(x+y)^(2n+2-n-1)
=2×﹙x+y)^(n+1)

Calculation: 2n + 1 power of 1 - (- 1) (n is an integer)=

2n + 1 is odd and the odd power of (- 1) is negative. 1 + 1 = 2

Calculate 1 * 3 / 1 + 2 * 4 / 1 + 3 * 5 / 1 + +48 * 1 / 50

1 / (1 * 3) = (1-1 / 3) * 1 / 21 / (2 * 4) = (1 / 2-1 / 4) * 1 / 2.1 / (48 * 50) = (1 / 48-1 / 50) * 1 / 2 original formula = 1 / 2 * [(1-1 / 3) + (1 / 2-1 / 4) + (1 / 3-1 / 5) +... + (1 / 47-1 / 49) + (1 / 48-1 / 50)] = 1 / 2 * (1 + 1 / 2-1 / 3 + 1 / 3-1 / 4 + 1 / 4. - 1 / 47 + 1 / 47-1 / 48 + 1 / 48-1 / 49-1 / 50) = 1 / 2 * (1 +

A rectangle is three fifths of its length and three fifths of its width. How many square meters is its area?

Area = length × width
=3/5×3/5×3/5
=27 / 125 M2

(1) 5 square meters: 15 square decimeters (2) two thirds of an hour: 45 minutes (3) 0.65kg: 855G (ratio)

(1) 5 square meters: 15 square decimeters = 500:15 = 100:3 = 100 / 3
(2) Two thirds of an hour: 45 minutes = 40:45 = 8:9 = 8 / 9
(3) 65 kg: 855G = 650:855 = 130:171 = 130 / 171
