Answer:
The answer is C one solution
Step-by-step explanation:
x-y=-14
-y=-x-14 bring x to the other side
y=x+14 divide everything by -1
-x-y=14
-y=x+14 bring x to the other side
y=-x-14 divide everything by -1
Well the rule for bases with multiple exponents is:
((a^b)^c)^d = a^(b*c*d)
So in this case we have:
(((x^(1/3))^4)^5
x^(4*5*1/3)
x^(20/3)
The "transformation" for a base being raised to multiple exponents is to raise the base to the power of the product of all exponents.
Since pi is irrational and it is used in the formula, we cannot give an exact answer except in terms of pi (we can give an aproxamation using 3.14 =aprox pi, but it is not exact)
ok
circumfernce=2pir
r=15
circumference=2pi15
circumference=30pi
exact=30pi cm
if you want to aprox pi=3.14 then
aprox circumfernce=94.2 cm
