New operation of mathematics problem definition For any two integers a and B, there are two operations defined: a △ B = a + B-1, A * b = B power of a - 1. Try to find the value of 2 * [(3 △ 4) △ (2 * 1)] Note: * is not an operational symbol For any two integers a and B, there are two operations defined: a △ B = a + B-1, A * b = B power of a - 1. Try to find the value of 2 * [(3 △ 4) △ (2 * 1)] Note: * is not an operational symbol Thank you

2 * [(3 △ 4) △ (2 * 1)] = 2 * [(3 + 4-1) △ (1 power of 2-1)] = 2 * [6 △ 1]=
The sixth power of 2 * [6 + 1-1] = 2 * 6 = 2-1 = 63

In the handicraft class, Mr. Tang asked the students to cut an isosceles right triangle (as shown in the figure) from one corner of a rectangular paper. What is the area of the remaining part?

15 × 11 - (11-3) × (11-3) △ 2, = 165-8 × 8 △ 2, = 165-32 = 133 (square centimeter). A: the area of the rest is 133 square centimeter

The total resistance of the series circuit is () higher than that of any partial resistance, which is equivalent to increasing the resistance of the conductor

It is equivalent to increasing the length of conductor r = R1 + R2 + R3 + +
Therefore, the resistance value of the total resistance is smaller than any other value in parallel because it is equivalent to increasing the cross-sectional area of the conductor. 1 / r = 1 / R1 + 1 / r2 + 1 / R3 +

How to change arcsiny = arcsinx + C into y = form

Add sin to the left and right, even if y = sin (arcsinx + C)

What is the square area formula

Square area = side length × side length

Given a + B + C = 3. A square + b square + C square = 29. A cube + B cube + C cube = 45, find a quartic + B quartic + C quartic

a+b+c=3a²+b²+c²=29a³+b³+c³=45(a+b+c)²=a²+b²+c²+2(ab+ac+bc)=3²=9∴29+2(ab+ac+bc)=9∴ab+ac+bc=-10(a+b+c)³=a³+b³+c³+3(a²b+a...

For ∫ f (x-1) DX, the integral interval is 0 to 2
It is known that f (x) = 1 / (1 + x) x > = 0;
1/(1+e^x) x=0;
1/1+e^(x+1) x

You can do that, but
The integral interval needs to be changed

There are five square tablecloths, each of which is 9 decimeters long. How many decimeters of lace do you need? How many meters do you need?

4×9×5＝180

Saw a 2-meter-long timber into three sections, the surface area increased by 24 square centimeters, and calculated the volume of cylindrical timber,

Saw into three sections, the surface area increased by 4 sections
2 m = 200 cm
1 cross section area = 24 (3 × 2-2) = 6 square centimeter
Volume of cylinder wood = 200 × 6 = 1200 cubic centimeter
