Question

a. (7x2 - y)2
b. (5mn2 + 8)2
c. (3x3 - 4y)2
d. (2a5 - 6b2c)2
e. (10m3n + n2)2
f. (4x2nyn - 5xn +1) 2

Answer 1

Explicación paso a paso:

$(7{y}^{2} - 2)2 = (2 \times 7) {y}^{2} - (2 \times y)= 14 {y}^{2} - 2y$

$(5m {n}^{2} + 8)2 = (2 \times 5)m {n}^{2} + (8 \times 2) = 10m {n}^{2} + 16$

$(3 {x}^{3} - 4y)2 = (2 \times 3) {x}^{3} - (4 \times 2)y = 3 {x}^{3} - 6y$

$(2 {a}^{5} - 6 {b}^{2} c)2 = (2 \times 2) {a}^{5} - (2 \times 6) {b}^{2} c = 10 {a}^{5} - 12 {b}^{2} bc$
