Answer:

-80-43i

Step-by-step explanation:

(8-3i)-(8-3i)(8+8i)

To find the value of the expression we need to simplify it

LEts multiply the parenthesis part using FOIL method

(8-3i)-(64+64i-24i-24i^2)

(8-3i)-(64+40i-24i^2)

The value of i^2 is -1

(8-3i)-(64+40i-24(-1))

(8-3i)-(64+40i+24)

(8-3i)-(88+40i)

Now we remove the parenthesis

8-3i-88-40i

combine like terms

-80-43i

Chen writes down a two digit number. He finds out that if he swapped the numbers, it would be three more than the 1/3 of the ori
inna [77]

Answer:

Step-by-step explanation:

From the information given,

Let the two digits that Chen writes down to be p and q

where,

q will be in the unit place and p will be in the tens place.

So, the value of the digit = 10p + q

So, if he swapped the number, he will have 10q + p

However,

the new number determined is thrice more than the 1/3 pf the original number.

i.e

the 1/3rd of the original number = \dfrac{1}{3}(10p+q)

=\dfrac{10p+q}{3}

thrice more than that will be = \dfrac{10p+q}{3} + 3

∴

\dfrac{10p+q}{3} + 3 = 10q+p

multiply through by 3, we have :

10p+q + 9 = 30q + 3p

collecting the like terms, we have:

10p - 3p +q -30q +9 = 0

7p - 29q +9 = 0

7p - 29q = -9

Therefore, p,q lie between 0 and 9

Therefore, the possibility of the original number is p = 7 and q = 2
