Question

How do you simplify `\frac { 28b ^ { 4} } { 14b ^ { 4} }`?

Answer 1

See a solution process below:

Explanation:

First, rewrite this expression as:

`(28/14)(b^4/b^4) => (28/14)(color(red)(cancel(color(black)(b^4)))/color(red)(cancel(color(black)(b^4)))) => 28/14 =>`

`(14 xx 2)/(14 xx 1) => (color(red)(cancel(color(black)(14))) xx 2)/(color(red)(cancel(color(black)(14))) xx 1) => 2/1 => 2`
