If 2x⁴ + 2y⁴ + 2z⁴ = 144, what is the mean of x⁴, y⁴ and z⁴

Margarita [4]

Answer: 24

Step-by-step explanation:

Given

$2x^4+2y^4+2z^4=144$

dividing whole equation by 2, we get

$\Rightarrow x^4+y^4+z^4=72$

Mean is given by the sum of the value of entities divided by the total no of entities

$\Rightarrow \text{Mean}=\dfrac{x^4+y^4+z^4}{3}\\\\\Rightarrow \text{Mean}=\dfrac{72}{3}\\\\\Rightarrow \text{Mean}=24$

Are 16:14 and 64:60 equivalent? Explain ???

zzz [600]

If a:b=c:d then a/b=c/d and ad=bc

so

if 16:14=64:60 then 16/14=64/60 and (16)(60)=(14)(64)
(16)(60)=960
(14)(64)=896
960≠896

not equivilent

the easiest way is to simplify them
16/14=8/7
64/60=32/30=16/15
not equal

not equivilent
