Anuta_ua [19.1K]

Answer:

n³ · s³ · 2²

Step-by-step explanation:

Hi!

An exponent is determined by the number of copies by any set number(n.)

I your case, all we have to do is count the number of each variable and number and that will be what the power(exponent) will be.

n: 3

s: 3

2: 2

So we will have n³ · s³ · 2² according to the piece of information shown above.

Thus, the answer to your question is $\boxed{n^{3} \cdot s^{3} \cdot 2^{2}}$ .

Hope this helps!

If f(x)x+12 and g( x)-2x, what is the value of (f -g)(144)?

serg [7]

First, we want to subtract function f minus function g to get a new function:

(f-g)(x)= x+12 - (-2x)
(f-g)(x)= x+12+2x
(f-g)(x)= 3x+12

Now, we want to plug in 144 for x:

(f-g)(144)=(3)(144)+12
(f-g)(144)=432 +12
(f-g)(144)=444

Therefore, the answer is 444
