Answer 1

Step-by-step explanation:

                   KNOWLEDGE BOOSTER

First Solve The Brackets And Then Do The Other Operations Using BODMAS.

BODMAS = Brackets (If there are two brackets in 1 question, solve the bracket which comes first and then solve the bracket which comes second) ⇒ Operation (Do the operation according to the symbol) ⇒ Division ⇒ Multiplication ⇒ Addition ⇒ Subtraction.

Follow all these steps to get the answer correct.

(a) $5x^{2} y - (5x^{2} +3yx^{2} -3y^{2} )+(x^{2} -y^{2} +8xy^{2} )$

⇒ $5x^{2} y - 5x^{2} +3yx^{2} -3y^{2} +x^{2} -y^{2} +8xy^{2}$

= $x^{2} y^{2} + yx^{2} y^{2} + x^{2} y^{2} +8xy^{2}$

(b) $5m^{2} -(5n^{2}+3m-3mn )+(m^{2} n^{2}+8mn )$

⇒ $5m^{2} -5n^{2}+3m-3mn +m^{2} n^{2}+8mn$

= $m^{2} n^{2} + mmn+m^{2} n^{2} +8mn$
