√25

Find factors of 25

25 = 5 x 5

Because there are two of the same numbers, move the two same factors outside the root, and make it one whole number

√25 = √5 x √5 = 5

5 is your answer

hope this helps

|3 + y| - 4 = 7 solve

vfiekz [6]

Answer:

y = 8 or y = -14

Step-by-step explanation:

Solve for y over the real numbers:

abs(y + 3) - 4 = 7

Add 4 to both sides:

abs(y + 3) = 11

Split the equation into two possible cases:

y + 3 = 11 or y + 3 = -11

Subtract 3 from both sides:

y = 8 or y + 3 = -11

Subtract 3 from both sides:

Answer: y = 8 or y = -14

How do I even start this? And how to i order the equation to solve

Kobotan [32]

$f(g(h(x)))=f(g(\sqrt x))=f(\sqrt x-1)=\boxed{(\sqrt x-1)^4+4}$

This is because

$h(x)=\sqrt x$

$g(x)=x-1$

$\implies g(h(x))=\sqrt x-1$

(that is, replace any instance of x in the definition of g with √x )

and

$f(x)=x^4+4$

$\implies f(\sqrt x-1)=(\sqrt x-1)^4+4$

(replace any x in f with √x - 1)

Also acceptable:

$(\sqrt x-1)^4+4=((\sqrt x)^4-4(\sqrt x)^3+6(\sqrt x)^2-4\sqrt x+1)+4$

$=\boxed{x^2-4x\sqrt x+6x-4\sqrt x+5}$

(assuming x is not negative)
