Question

Comparati numerele a si b, unde : a= (3,5+0,5)(3,5-0,5) si b= (0,1 la puterea 2) totul la puterea 3 : 0,1 la puterea 3 + 0,2 la puterea 3 * 10 la puterea 3

Answer 1

Answer 2

a=(3,5+0,5)(3,5-0,5)=formula (a+b)(a-b)=a^2-b^2=3,5^2- 0,5^2=12,25-0,25=12
b=(0,1)^2)^3 / 0,1^3+0,2^3x10 ^3=(o,1)^6/ 0,001+0,008 x1000=0,000001/0,001+8=0,01+8=8,01
a>b  12>8,01
