Subtract 7a^4-4a^2b^2+67a 4 −4a 2 b 2 +6 from 3a^4+2ab^2+113a 4 +2ab 2 +11.

Step-by-step explanation:

The given equation is

            .................(i)

we have to subtract it from

            .................(ii)

First we will take the same terms of the equations in it and solve them

taking equation (i) and solving the similar terms

=     .......................................(iii)

taking equation (ii) and solving similar terms

=      ......................................(iv)

Now we have to subtract (iii) from (iv)

which will be

=-

=  

adding and subtracting the similar terms will give us

=

this is the required answer  

Step-by-step explanation:

Subtract from

Lets arrange the terms in order and then subtract. when we subtract we change the sign of each term in second parenthesis

Now we combine like terms

The final expression is

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
