For which value of x must the expression square root of 19x be further simplified?

x is a multiple of 19

Step-by-step explanation:

Given is a square root as

We know that 19 is prime and has factors only as itself and 1

Factors of 19 are 19 and 1

If square root term is to be simplified there must be atleast one factor which is repeated twice.

In 19x, since 19 is prime if we want a factor to be repeated then it can be 19

This is possible only if x is a multiple of 19

Hence answer is whenever x = 19m for some natural number m, we can simplify the square root sign.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

f(x)=2/3x-8, which give g(x) the greatest value.
