Answer:

-9

Step-by-step explanation:

( \sqrt[4]{7}  + 2)( \sqrt[4]{7}  - 2)( \sqrt{7}  + 4) \\  = ( { \sqrt[4]{7} }^{2}  - {{2} }^{2} )( \sqrt{7}  + 4) [because (a+b)(a-b) = a² - b²]\\  = ( \sqrt{7}  - 4)( \sqrt{7}  + 4) \\  =   { \sqrt{7} }^{2}  -  {4}^{2}[because (a+b)(a-b) = a² - b²]  \\  = 7 - 16 \\  =  - 9

Remember you can add like terms exg, 3y+4y=7y 3y^2+4y^2=7y^2, but cannot add 3y^2 and 4y, or 3 and 4y so

3a+2w-5a-9w
group like trems
3a-5a+2w-9w
subtract
-2a-7w


3y^2+2w^2-y^2-w^2
group like terms (think of w^2 and y^2 as 1w^2 and 1y^2)
3y^2-y^2+2w^2-w^2
subtract
2y^2+w^2

2x+2x=4x
