Trzeba obliczyć dwa przykłady. (skan przykładów w załączniku)
Prosze o dokładne rozpisanie co jak i po koleji .
a)
(-1,4) : 7/5 - 3,6 * (-1/3²) + 2i2/3 √2i1/4 =
-1i2/5 * 5/7 - 3i3/5 * (-1/9) + 8/3 √9/4 =
-7/5 * 5/7 - 18/5 * (-1/9) + 8/3 * 3/2 =
-1 + 2/5 + 4 =
-1 + 0,4 + 4 =
-0,6 + 4 =
3,4
b)
2√8 - (1,6:2) ⁻¹ + (√2-2)² =
2√(4*2) - (4/5)⁻¹ + (2-4√2+4) =
2*2√2 - 5/4 + (6-4√2) =
4√2 - 1,25 + 6 - 4√2 =
6 - 1,25 =
4,75
a)=-7/5:7/5+3,6/9+2 2/3*√9/4=
-1+0,4+8/3*3/2=-1+0,4+4=3,4
b)=4√2-(10/8)+2-4√2+4=1 i 2/8+6=7 i 2/8
