Answer:
z^5
Step-by-step explanation:
z^8 * z^-3
Since we are multiplying exponents and the bases are the same, we can add the exponents
z^(8-3)
z^5
Cos35= y/15
y= 15cos35
y= 12.3 cm
Answer:
We cannot solve without a value for x. The simplified form is 
Step-by-step explanation:
If the equation is
then we cannot solve it until we know the value of x. We can simplify it using order of operations such as PEMDAS.
