Here they are:

*1. Use 9 bits for*

(a) 843434343488

(b) 43553.99786763

(c) 0.00000000487

(d) 0.2345899

**mantissa**and 3 bits for**exponent**to represent the following numbers:(a) 843434343488

(b) 43553.99786763

(c) 0.00000000487

(d) 0.2345899

**My answer:**

(a) 843434343488 = 0.843434343

|8|4|3|4|3|4

**|**3|4|3|

(b) 43553.99786763 = 0.4355399786763 x 10^5

|4|3|5|5|4|0

**|**0|7|8|

(c) 0.00000000487 = 0.487 x 10^-8

|0|0|0|0|4|9

**|**0|0|0|

(d) 0.2345899 = 0.2345899 x 10^1

|2|3|4|6|0|0

**|**0|0|1|

*2. Use*

**fixed-point**notation and 9 bits to multiply and store the following numbers 564.3 and 45.666.**My answer:**

564.3 = 5.643 x 10²

45.666 = 4.5666 x 10¹

*3. Use 7 bits for mantissa and 2 bits for exponent and Floating-point notation to simplify and store the following:*

(a) 355.898 + 4564.56

(b) 456 – 44.3555

(a) 355.898 + 4564.56

(b) 456 – 44.3555

**My answer:**

(a) 355.898 + 4564.56 = 4920.458

= 4920458 x 10^4

|4|9|2|0|4

**|**6|0|

(b) 456 – 44.3555 = 411.6445

= 4116445 x 10^3

|4|1|1|6|4

**|**5|0|
