Answer:
308[cos(45) + isin(45)]
Step-by-step explanation:
z1×z2:
Modulus: r1 × r2
= 7×44 = 308
Argument: theta1 + theta2
= -70 + 115 = 45
z1z2 = 308[cos(45) + isin(45)]
Or
z1z2 = 154sqrt(2) + (i)154sqrt(2)
sqrt: square root
The value of 1 in 178 is 100 since it is in the hundreds place. The value of 7 in 178 is 70 and the value of 8 in 178 is 8. The hundreds place carries numbers from 1 to 9. Once you get to 10, you add a digit to the number such that you now have four total numbers and the first digit is in the thousands place.
