Simplify : (√ + √ ) (√ − √) ( + )( 2 + 2 )

jek_recluse [69]

$(\sqrt{x}+\sqrt{y})(\sqrt{x}-\sqrt{y})(x+y)(x^2+y^2)\\\\=[(\sqrt{x})^2-(\sqrt{y})^2](x+y)(x^2+y^2)\\\\=(x-y)(x+y)(x^2+y^2)\\\\=(x^2-y^2)(x^2+y^2)\\\\=(x^2)^2-(y^2)^2\\\\=x^4-y^4$

$Used:\\\\(\sqrt{a})^2=a\\\\(a-b)(a+b)=a^2-b^2\\\\(a^n)^m=a^{nm}$

Write a linear function f with f(−10)=4 and f(−2)=4. f(x)=

ZanzabumX [31]

Answer:

f(x) = 4

Step-by-step explanation:

Let us assume that the linear function f(x) = ax + b

Here, we have to find the value of a and b to know the function.

Given that f(-10) = 4 and f(-2) = 4

So, -10a + b = 4 ....... (1) and

-2a + b = 4 .......... (2)

From equations (1) and (2) we get a = 0 and b = 4.

So, the linear function is f(x) = 4. (Answer)
