Question

si a4b000=k^3,determina el valor de (a+b)^2 ayuda estoy en practica

Answer 1

Respuesta:

a (a + 2 b) + b^2

a^2 + b (2 a + b)

Expanded form:

a^2 + 2 a b + b^2

Real root:

b = -a

Root:

b = -a

Polynomial discriminant:

Δ = 0

Property as a function:

Parity

even

Derivative:

d/da((a + b)^2) = 2 (a + b)

Indefinite integral:

integral(a + b)^2 da = 1/3 (a + b)^3 + constant

Global minima:

min{(a + b)^2} = 0 for b = -a

Definite integral over a disk of radius R:

integral integral_(a^2 + b^2<R^2) (a + b)^2 da db = (π R^4)/2

Definite integral over a square of edge length 2 L:

integral_(-L)^L integral_(-L)^L (a + b)^2 db da = (8 L^4)/3

Answer 2

Respuesta: 36

Explicación paso a paso:

k = 70

a = 3

b = 3

k^3 = 343000

(a+b)^2 = 36
