I need help with this plz
Anni [7]

Answer:

exponent of x is 33

exponent of y is 0

Step-by-step explanation:

you need to combine all powers (exponents) of x, and all exponents of y separately.

remember : x to the power of a divided by x to the power of b is x to the power of (a-b).

when multiplying, the "-" turns into a "+".

so, we have actually for x the exponent calculation :

8 - 14 -(-39) = 8 - 14 + 39 = 33

so, x³³ remains.

and for the y exponents

-26 -(-5) -(-21) = -26 + 5 + 21 = 0

so, all the y expressions eliminate each other and y⁰ remains.

<h3>d) </h3><h3>2 ({(2x)}^{2}  +  {(3y)}^{2} ) \\</h3>

Step-by-step explanation:

{(2x + 3y)}^{2}  +  {(2x - 3y)}^{2}  \\ (2x + 3y)(2x + 3y) + (2x - 3y)(2x - 3y) \\ 2x(2x + 3y) + 3y(2x + 3y) + 2x(2x - 3y) - 3y(2x - 3y) \\  {4x}^{2}  + 6xy + 6xy +  {9y}^{2}  +  {4x}^{2}  - 6xy - 6xy  +  {9y}^{2}  \\  {4x}^{2}  + 12xy +  {9y}^{2}  +  {4x}^{2}  - 12xy   +   {9y}^{2}  \\  {4x}^{2} +  {9y}^{2}   +  {4x}^{2}   +  {9y}^{2} \\ {8x}^{2}  +  {18y}^{2}  \\ 2( {4x}^{2}  +  {9y}^{2} ) \\ 2( {2}^{2}  {x}^{2}  +  {3}^{2}  {y}^{2} ) \\ 2({(2x)}^{2} + {(3y)}^{2}) \\
