Question

calculati media aridmetica si geometrica a numerelor: d=2-√3 si b =2+√3

 

urgenttt!!!!  daca se pate si cu explicatie!!!

 

Answer 1

media aritmetica = (d+b)/2 = (2-√3 + 2+√3)/2=4:2=2
media geometrica = $\sqrt{(2+ \sqrt{3} )*(2- \sqrt{3} )}$
aplic formula (a-b)*(a+b)=$a^{2} - b^{2}$
Rezulta media geometrica = $\sqrt{ 2^{2} - \sqrt{3} ^{2} } = \sqrt{4-3} =1$

Answer 2

M aritmetica=a+b÷2= 2+√3+2-√3÷2=4÷2=2
M geometrica= √a×√b= √2+√3×√2-√3=√4-3=√1=1
