Question

1) 36x^ 2 y^ 2 -1; 2) x ^ 2 y ^ 2 - 16; 3) 81a ^ 6 - 49b ^4; 4) 25a ^ 2 - 9b ^ 6 Пажалуйста помогите срочно

Answer 1

1) 36x^2y^2-1 = (6ху-1)*(6ху+1)

2) x^2y^2-16 = (ху-4)*(ху+4)

3) 81a^6-49b^4 = (9а^3-7b^2)*(9а^3+7b^2)

4) 25a^2-9b^6 = (5а-3b^3)*(5а+3b^3)

Answer 3

1) To simplify the expression 36x^2 + y^2 - 1, we can't simplify it further because there are no like terms to combine. So the expression remains as it is.

2) To simplify the expression x^2 + y^2 - 16, we can't simplify it further because there are no like terms to combine. So the expression remains as it is.

3) To simplify the expression 81a^6 - 49b^4, we can't simplify it further because there are no like terms to combine. So the expression remains as it is.

4) To simplify the expression 25a^2 - 9b^6, we can't simplify it further because there are no like terms to combine. So the expression remains as it is.
