98 points! (3x^2^a - 4y^a z^3a )^2

((3x^2)^a - (4y^a)(z^3a))^2

First, expand.

((3x^2)^a - (4y^a)(z^3a)) ((3x^2)^a - (4y^a)(z^3a))

Combine

3^(2a) - x^(4a) - 8 * 3^(2a)x^(2a)y^(a)z^(3a) + 16y^(3a)z^(6a)

hope this helps

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
