i dont no 44444 but thanks for the points
You can turn it into a mixed number 1 83
--
100
-1+z because 7-8 would be -1 and positive 3-3 would just be the variable after
the given expression is :
2(4√16x) - 2(4√2y) + 34√81x - 4(4√32y)
⇒ 8(√16x) - 8(√2y) + 34√81x - 16√32y
⇒8×4√x - 8√2y + 34×9√x - 16√16×2y [∵ √16 = 4 and √81 = 9]
⇒32√x - 8√2y + 306√x - 16×4√2y
⇒(32√x + 306√x) - 8√2y - 16×4√2y
⇒338√x -72√2y
When comparing these two sets of number, the first set is harder to find the different as you need to borrow from a column. For instance, when you start subtracting in the 10s place, you cannot take 40 away from 30.
Whereas in the second set, comparing the numbers is easy. They have the same 100s value and the same 10s value. You are simply comparing the 1s place.
