Give a mathematical example to show the following:

-(m/n) = (m/n)^-1 = 1 / (m/n)

Hence, a^-(m/n) = (1 / a^(m/n)) where m,n are rational numbers.

For example: let 1/2 be rational number and 4 be real number then, 4^-(1/2) = 0.5 = 1/(4^(1/2))

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
