(2x^2+3x-7)(5x+4)

Simplify: ((sqrt(2))/(5))^(8)-:((sqrt(2))/(5))^(13) (ii) ((5^(-1)x7^(2))/(5^(2)x7^(-7)))^((1)/(2))x((5^(-2)x7^(3))/(5^(3)x7^(-5)))^(-(5)/(2))

Find each of the following products: (i) (x + 6) (x + 6) (ii) (4x + 5y) (4x + 5y) (iii) (7a + 9b) (7a + 9b) (iv) ((2)/(3) x + (4)/(5)y) ((2)/(3) x + (4)/(5) y) (v) (x^(2) + 7)(x^(2) + 7) (vi) ((5)/(6) a^(2) + 2) ((5)/(6) a^(2) + 2)

(2x-(7-5x))/(9x-(3+4x))=(7)/(6)

7-3((2x-5))/(4)=(1)/(2)(4x-7)

Simplify: ((1)/(4)x(2)/(7))-((5)/(14)x(-2)/(3))+((3)/(7)x(9)/(2))

int (x^(2) +1)sqrt(x+1)dx is equal to a) ((x+1)^(7//2))/(7) - 2((x+1)^(5//2))/(5) + 2((x+1)^(3//2))/(3)+c b) 2[((x+1)^(7//2))/(7) - 2((x+1)^(5//2))/(5) + 2((x+1)^(3//2))/(3)]+c c) ((x+1)^(7//2))/(7) - 2((x+1)^(5//2))/(5) + c d) ((x+ 7)^(7//2))/(7) - 3((x+1)^(5//2))/(5) + 11(x+1)^(1//2)+c

(3x-4)/(7)+(7)/(3x-4)=(5)/(2)
