Question

4ab(squared)-3ab(squared)

directions: simplify the expression using only positive exponents in your answer

Answer 1

I guess you mean
\[4a(b^2) - 3a(b^2)\]right?

If so, this simplifies to
\[a(b^2)\]

Answer 2

thats right, but i just dont know how to do squared on the computer lol but is there anyway you could possibly explain to me how you got that, so i can understand better>

Answer 3

Yep, you can think of
\[a(b^2)\]as being an item on its own, so you're taking 3 of those items from 4 of them. Algebraically this can be written as:
\[4*a(b^2)-3*a(b^2) = (4-3)*(a(b^2))\]Which equals:
\[(1)*a(b^2) = a(b^2)\]Hopefully that clears things up a bit.

Answer 4

it definately did. thanks!

Answer 5

No problem!
