Step-by-step explanation:

Answer 2

Answer:

So as we know the formula which relates all components in division which is :

Dividend= Divisor * quotient + remainder

So in this case we know

Divisor= 8

Remainder= 5

Now both quotient and dividend are unknown

So let dividend be y and quotient be x

The formula now becomes:

y=8x +5. … eq1

Now the remainder when the unknown no. y² is divided by 8 is required so

Step 1

Square equation 1

We get y² = 64x² + 80x + 25

Now convert it into a form taking 8 as common something like this

y²= 64x² + 80x + 24 +1

Now taking common from the equation

y²= 8( 8x²+ 10x +3 ) +1

Now this is comparable to our base equation where

Dividend= Divisor * quotient + remainder

On comparison we will realise that remainder is 1.
