Question

Simplify the following. (a) 3(-3 + 5x) - 1 (4 - 4x) (b) 3 squareroot 64 x^15 y^3 -2(-15 e^5 t/30 e^-2 t^-3)^0

Answer 1

a. 19x-13 b.
`2(32x^(15)y^(3)-1).`

Explanation:

a. 3(-3+5x)-1(4-4x) = -9+15x-4+4x = 15x+4x-9-4 = 19x-13.

b.
`64x^(15)y^(3)-2(-15e^(5)(t)/(30)e^(-2)t^(-3))^(0)`

=
`64x^(15)y^(3)-2 = 2(32x^(15)y^(3)-1).`
