Simplify write with only positive exponents! asap and don’t delete the question i need with it so bad! : (

b^(10/3)/a^3

Two rules of exponents are involved:

... a^-b = 1/a^b

... (a^b)^c = a^(bc)

Here, this means we can rewrite the given expression as ...

... (a^(4/5)/b^(8/9))^(-15/4) = a^(4/5·(-15/4))/b^(8/9·(-15/4)) . . . . . multiply outer exponent by inner exponents per 2nd rule

... = a^-3/b^(-10/3) . . . . simplify the exponents

... = b^(10/3)/a^3 . . . . . swap numerator and denominator and change exponent signs per 1st rule

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
