Question

Simplify each expression.

Answer 1

3) 7
`(7)/(5(n+2))`

5)
`(9)/(k+2)`

7)
`(7b)/(b-9)`

Explanation:

3)
`(7n+5*7)/(5n^(2)+(5*7)n+2*5^(2)  )`

`(7((7n)/(7)+(5*7)/(7) ) )/(5((5n^(2) )/(5)+(5*7n)/(5)+(2*5^(2) )/(5)   ))`

5)
`(3^(2)(k+5) )/(k+2) * (1)/(k+5)`

7)
`(5*7*b^(2)+7^(2*b) )/((2*5)b+2*7)` /
`(b-9)/(2)`

`(7b ((5*7b^(2) )/(7b) + (7^(2)*b )/(7b) ))/(2((2*5b)/(2)+(2*7)/(2)) )` /
`(b-9)/(2)`

This is my first time using the equation function, hopefully I did it correct.
