This expression without exponents is 8a^3.

(2a)^3

= (2a)(2a)(2a)

= 8a^3

(2a)^3

= (2a)(2a)(2a)

= 8a^3

The standard form the equation of the given line. The line that passes through (-2, 4) and is parallel to x - 2y = 6 is x - 2y = -10.

slope of x - 2y = 6 is 1/2;

y - 4 = 1/2(x + 2);

2y - 8 = x + 2;

x - 2y = -10

slope of x - 2y = 6 is 1/2;

y - 4 = 1/2(x + 2);

2y - 8 = x + 2;

x - 2y = -10
