There is no such formula

The derivative of a function is obtained by logarithmic differentiation
The square of the x power of y = x
Y = x to the power of X;.

y=(x^x)²=x^2x
lny=2xlnx
Derivation
(1/y)*y'=2lnx+2x*1/x=2lnx+2
So y '= x ^ 2x * (2lnx + 2)

In a 20 cm cube glass container with a water depth of 10 cm, a rectangular iron block with a length and width of 8 cm and a height of 15 cm should be placed in the container. If the iron block is placed vertically in the water, how many cm will the water surface rise

The volume of rising iron
(15 * 8 * 8) / 20 * 20 = 2.4cm

Find the rules:
(1—1/2）*（1+1/2）*（1—1/3）*（1+1/3）*（1—1/4)*（1+1/4)=
What are the rules?

(1—1/2）*（1+1/2）*（1—1/3）*（1+1/3）*（1—1/4)*（1+1/4)=1/2×3/2×2/3×4/3×3/4×5/4=5/8(1—1/2）*（1+1/2）*（1—1/3）*（1+1/3）*（1—1/4)*（1+1/4)×…… ×（1-1/n）（1+1/n）=（n+1）/（2n）...

Give a pair of quantities with opposite meanings and express them with positive and negative numbers respectively______ ．

For example, if you move 2 meters to the East, it will be recorded as + 2 meters, and if you move 2 meters to the west, it will be recorded as - 2 meters (the answer is not unique). Therefore, the answer is: if you move 2 meters to the East, it will be recorded as + 2 meters, and if you move 2 meters to the west, it will be recorded as - 2 meters (the answer is not unique)

What are the categories of numbers in mathematics

(0.911 cycle + 0.822 cycle + 0.733 cycle + 0.644 cycle) - (0.11 cycle + 0.22 cycle + 0.33 cycle + 0.44 cycle + 0.5 cycle)
(0.911 cycle + 0.822 cycle + 0.733 cycle + 0.644 cycle) - (0.11 cycle + 0.22 cycle + 0.33 cycle + 0.44 cycle + 0.55 cycle + 0.66 cycle) also need to be improved

(0.911 cycle + 0.822 cycle + 0.733 cycle + 0.644 cycle) - (0.11 cycle + 0.22 cycle + 0.33 cycle + 0.44 cycle + 0.55 cycle + 0.66 cycle) = (0.9 + 0.8 + 0.7 + 0.6) + (1 / 90 + 2 / 90 + 3 / 90 + 4 / 90) - (1 / 9 + 2 / 9 + 3 / 9 + 4 / 9 + 5 / 9 + 6 / 9) = 3 + 1 / 9-7 / 3 = 7 / 9
