4^-3
You first need to make the exponent positive. To do this put it in a fraction.
1/4^3
Now solve the exponent.
4 * 4 * 4 =
^
16*4 = 64
1/64 is your answer
10 windows : divide 40/5=8

Answer:
Step-by-step explanation:
So we have the two functions:
And we want to find f(g(1)).
So, let's find g(1) first:
Substitute 1 for x:
Simplify:
Add:
So:
Now, substitute 2 for x in f(x):
Multiply:
Add:
So:
Answer:
Step-by-step explanation:
6x + ( 14x - 5 ) + ( 17 - 3x )
= 17x + 12
- ( 2 - x ) -3 ( 6 + 8x ) -12,
= -23x - 32
( 4x - 9 ) + 8 ( 2x + 3 ) -7x
= 13x +15
