$8 x$ $8x$ = $200$ $200$

We can logic here: $8 x$ $8x$ is twice of $4 x$ $4x$ , hence $8 x$ $8x$ = $2 \times 4 x$ $2 xx 4x$ = $2 \times 100$ $2 xx 100$ = $200$ $200$ .

OR

Find $x$ $x$ :

$4 x = 100$ $4x = 100$
$x = \frac{100}{4}$ $x = 100/4$
$x = 25$ $x = 25$

Therefore $8 x$ $8x$ = $8 \times 25 = 200$ $8 xx 25 = 200$

So, $8 x$ $8x$ = $200$ $200$

If 4x=1004x=100, what is 8x8x?
