Answer:
590000000
63500
9010000
1120
830000
459200000000
Step-by-step explanation:
Express each product as a numeral."
a) 5.9x10^8 = 5.9 * 100000000 = 590000000
b)6.35x10^4 = 6.35 * 10000 = 63500
C) 9.01x10^6 ) 9.01 * 1000000 = 9010000
D) 1.12x10^3 = 1.12 * 1000 = 1120
e) 8.3x10^5 = 8.3 * 100000 = 830000
f) 4.592x10^11). 4.592 * 100000000000 = 459200000000
Answer:
761+100=861
Step-by-step explanation:
<span>we have that
the cube roots of 27(cos 330° + i sin 330°) will be
</span>∛[27(cos 330° + i sin 330°)]
we know that
e<span>^(ix)=cos x + isinx
therefore
</span>∛[27(cos 330° + i sin 330°)]------> ∛[27(e^(i330°))]-----> 3∛[(e^(i110°)³)]
3∛[(e^(i110°)³)]--------> 3e^(i110°)-------------> 3[cos 110° + i sin 110°]
z1=3[cos 110° + i sin 110°]
cube root in complex number, divide angle by 3
360nº/3 = 120nº --> add 120º for z2 angle, again for z3
<span>therefore
</span>
z2=3[cos ((110°+120°) + i sin (110°+120°)]------ > 3[cos 230° + i sin 230°]
z3=3[cos (230°+120°) + i sin (230°+120°)]--------> 3[cos 350° + i sin 350°]
<span>
the answer is
</span>z1=3[cos 110° + i sin 110°]<span>
</span>z2=3[cos 230° + i sin 230°]
z3=3[cos 350° + i sin 350°]<span>
