Given that the x power of 10 = 2 and the Y power of 10 = 3, find the value of 3x-2y of 10 The answer is tonight

Given that the x power of 10 = 2 and the Y power of 10 = 3, find the value of 3x-2y of 10 The answer is tonight

10^(3x-2y)
=10^(3x)/10^(2y)
=(10^x)^3/(10^y)^2
=2^3/3^2
=8/9

Given 3x-2y-3 = 0, find the 3x power of 10 ÷ the 2Y power of 10

∵3x-2y-3=0
　∴3x-2y=3
　∴[10^(3x)]÷[10^(2y)]
　　=10^(3x-2y)
　　=10 ³
　　=1000

It is known that the x-th power of a = 3 and the y-th power of a = 5. Find the X-Y power of a and the 3x-2y power of A

a^(x-y)=a^x/a^y=3/5
a^(3x-2y)=a^(3y)/a^(2y)=3 ³/ five ²= 27/25

Given that the x power of 2 is equal to a and the Y power of 2 is equal to B, find the X + y power of 2 plus the 3x-2y power of 2

The X + y power of 2 plus the 3x-2y power of 2
=X power of 2 × Y power of 2 + 3x power of 2 ÷ 2Y power of 2
=ab+a ³/ b ²

Using MATLAB to draw the graph of the fourth power of x plus the fourth power of y = 1

It's very simple
ezplot('x^4+y^4-1',[-2 2 -2 2])
axis equal
The result is a rounded square
Circle can be used to verify:
ezplot('x^2+y^2-1',[-2 2 -2 2])
axis equal

How to input (x ^ 3-x ^ 2) cubic power in MATLAB

1. First, use the Syms function to declare x as a character, that is, SYMS X;
2. Enter the expression: x ^ 3-x ^ 2; In this way, you can get the expression you want directly
