# MCQs Number System First Year 4

The Post is about the MCQs Number System from Mathematics of Intermediate Part-I (First Year). Let us start with the Online Number System Quiz with Answers. MCQs are about the number system Test for the preparation of mathematics.

MCQs Mathematics covers the topic of the Number system for the preparation of Intermediate mathematics.

1. Real part of $(x+iy)^n$ is

2. The modulus of $z$ is

3. If $R$ is the set of real numbers, then product $R\times R$ is called

4. Polar form of $(\sqrt{3} + i)$ is

5. If $z=3-5i$ then $|z|^2$ is equal to

6. If $z_1=2+3i$, $z_2=1-i$ then $|z_1z_2|=$

7. The geometrical plane on which the coordinate system has been specified is called

8. If $|x+5i|=3$ then $x$ is equal to

9. Polar form of $1+i\sqrt{3}$ is

10. If a point $A$ of a coordinate plane corresponds to the ordered pair $(a, b)$, then $a$ and $b$ are called

11. If $z=x+iy$ then $|z|=? 12. The modulus value of a complex number$z=x+iy$is the distance from 13. Golden rule of fraction is that for$k\ne 0 $,$\frac{a}{b} =$14. If$z$is a real number then 15. The set$\{1, -1\}$possesses closure property w.r.t. 16. Imaginary part of$(-2+3i)^2$is equal to 17. If point$A$of the coordinate plane corresponds to the ordered pair$(a,b)$then 18. If$z=a+ib$then$(z^2+\overline{z}^2)$is equal to 19. The correct statement of De Mover’s Theorem is$(cos \theta + i\, sin\, \theta)^n$is equal to 20. 0.1428571428571…. is A numeral system is a way of expressing numbers; that is, it is a mathematical writing system or notation used to represent the numbers of a given set consistently by using either digits or other symbols. The same sequence of symbols may represent different numbers in different numeral systems. ### Decimal Number System The commonly used number system is the decimal positional numeral system. The decimal refers to 10 symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. These numbers are used to construct all other numbers such as 10, 11, 12, 13, and so on. In mathematics courses you have heard about number systems of whole numbers and real numbers, however, in the context of computer systems, the other types of number systems are (i) The decimal number system (Ten Symbols or Numbers), (ii) The binary number system (Two Numbers or Symbols), (iii) The octal number system (Eight Numbers or Symbols)and, (iv) The hexadecimal number system (Sixteen Numbers or Symbols). ### MCQs Number System First Year • Imaginary part of$(-2+3i)^2$is equal to • If$R$is the set of real numbers, then product$R\times R$is called • The geometrical plane on which the coordinate system has been specified is called • If a point$A$of a coordinate plane corresponds to the ordered pair$(a, b)$, then$a$and$b$are called • If point$A$of the coordinate plane corresponds to the ordered pair$(a,b)$then • The modulus value of a complex number$z=x+iy$is the distance from • If$z=x+iy$then$|z|=?
