=(16*x^2*y*4*x^5*y^2*z)^1/3= =(64*x^7*y^6*z)^1/3= =64^1/3*(x^7)^1/3*(y^6)^1/3*z^1/3= 4*x^(7/3)*y^2*z^1/3

HELPPP!! rate of change
(y-2)/(4-(-1))=-4/5

calculus2
You can change 1 and 0. The simplest example of non-integrable function are: 1/x in the interval [0, b]

calculus2
An example of this is the function that is 1 on any rational number and 0 elsewhere.

f(y)=1 when y not 0 f(y)=0 when y=0 g(x)=0 when x-is irrational number g(x)=1/p when x=q/p, p&q-coprime numbers f(g(x))=0 when x-is irrational f(g(x))=1 when x=q/p

Trigonometry
cos(76pi)=cos(74pi)=...=cos(2pi)=cos0=1 sec(23pi)=sec(21pi)=...=sec(3pi)=sec(pi)= -1 because the period T=2pi (If pi=n)

Math
log(20/9)=log20-log9=log10+log2-log9= =1+0.30-0.95

Math
The accumulation value at the end of nth period A=P(1+i)^n A=1000*1.09^8=1,992.56

Math
5000=2500*1.03^t 1.03^t=2 t=ln2/ln1.03=23.4
