Question

Write, in binary, the instruction that will
carry out the calculation 46 x 75.

Answer 1

Answer:

3450

Explanation:

46×75=(50-4)×(50+25)

=(50)^2+(25-4)50-4×25

= 2500+ 21×50-100

=2500+1050-100

=3550-100

=3450

(x-a)(x+b)=x^2+bx-ax-ab

=x^2+(b-a)x-ab

Answer 2

Answer:

10010000110011110

Explanation:

Given :

00 Add (op1 + op2)

01 Subtract (opt — op2)

10 Multiply (op 1 x op2)

11 Divide (opl op2)

Considering the example given

For Multiplication the OPCODE is 10

So, we can write it in binary form as:

x           op1              op2

             46              75

10      01000110     01110101
