Answer:

-20/3

Step-by-step explanation:

3/4r + 2 = -3

subtract 2 on both sides...

3/4r = -5

divide by 3/4 on both sides...

3/4r divided by 3/4 is r.

-5 divided by 3/4 is the same thing as...

-5 times 4/3 (flip the fraction)

-20/3

Hope this helps!

HELP! SIMPLIFY!

1)  (m³n⁵)(mn⁴)
     -----------------
      m⁻³n²

Simplify.

m⁴n⁹
-------
m⁻³n²

When the bottom power is a negative, you add it to the power on top, & when the power is a positive, you subtract it.

m⁴ + m³ = m⁷

n⁹ - n² = n⁷

So, our answer for #1 is m⁷n⁷

2)  6a²b³
     ---------
        4a

Please read rules in #1.

6 / 4 = 3/2 & a² - a = a

So, our answer is 3a
                               -----
                                 2

3)  5⁶a⁶b³
     ---------
       5²ab³
5⁶ - 5² = 5⁴ AND a⁶ - a = a⁵ AND b³-b³ = 0

So, our answer is 5⁴a⁵

Simplify 5⁴

5 × 5 × 5 × 5 = 625

So, our final answer is :

625a⁵
