PLEASE HELP Give me two rules of exponents that you have learned so far
in middle school maths, any basic rule would help thanks :)

Step-by-step explanation:

Multiplication:

Suppose we decide to use the base b and that we multiply b^a and b^c together.  The relevant rule of exponents tells us that the product is

b^(a + c).  In words, we add together the two exponents a and c.

Exponentiation:

Suppose we have b^c and wish to raise all of b^c to the power d.  The base remains the same:  It is b.   Starting with b^c, we enclose b^c inside parentheses and then raise the quantity inside parentheses to the power d:

(b^c)^d.  Note that this simplifies to b^(cd), in which we multiply the powers together.

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

a
