Answer 1

X= (9.1 * 10⁻²) * (8 * 10⁻³) = (9.1 * 8) * 10⁻²⁺⁽⁻³⁾ = 72.8 * 10⁻⁵ 
у= 0,000728 =  728/10⁶ = 72,8/10⁵ = 72,8 * 10⁻⁵
х=у

х= (4,8*10⁻³) * (6*10⁻⁴) = (4,8*6)*10⁻³⁺⁽⁻⁴⁾= 28,8 *10⁻⁷
у= 0,000000288 = 288/10⁹  = 28.8/10⁸= 28,8 * 10⁻⁸
х>y

x=(6.1 * 10⁻⁴) * (5*10⁻⁴) = 6.1 * 5 * 10⁻⁴⁺⁽⁻⁴⁾  = 30.5 * 10⁻⁸=3.05 * 10⁻⁷
y=0.0000003 = 3/10⁷= 3 * 10⁻⁷
x>y

Answer 2

А) x = 0,091 * 0,008 = 0.000728 
y = 0.000728 

они равны

б) x = 0,0048 * 0,0006 = 0.00000288
y = 0.000000288

y < x

в) x = 0,00061 * 0,0005 = 0.000000305
y = 0.0000003

x > y
