Question

Fill in the blanks:
8,943 = _______×20³+_______×20²+_______×20+_______×1

Answer 1

So in the blanks there will be 1 , 2, 7, 3

An the expression is
`8943=1* 20^3+2* 20^2+7* 20+3* 1`

Explanation:

We have given the expression
`8943=......* 20^3+.......* 20^2+......* 20+......* 1`

We know that
`20^3=8000`

When we multiply 8000 by 1 it will be 8000

We know that
`20^2=400` when we multiply 400 by 2

Then it will give 400×2 = 800

And 20×7 = 140

And 3×1 = 3

When we add all these numbers 8000+800+140+3 = 8943

So in the blanks there will be 1 , 2, 7, 3

An the expression is
`8943=1* 20^3+2* 20^2+7* 20+3* 1`
