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.

the answer is 14ft

step-by-step explanation:

problem:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

f(5/2) = 10/3

i hope this !
