Simplify the expression where possible. (r^-3 s^2 t)^4

lisabon 2012 [21]

Answer:

$\frac{(s^8t^4)}{r^{12}}$

Step-by-step explanation:

Assuming that you tried to write:

$(r^{-3} s^2 t)^4,$

we can multiply the 4 on the outside of the parenthesis to all the terms. Multiplying, we get

$(r^{-12}s^8t^4)$

Because you don't want any negative powers in the top, we can move it down to get:

$\frac{(s^8t^4)}{r^{12}}$

You need to find the width of the stream you cannot measure the width directly so you draw a diagram showing lengths that you ca

kap26 [50]

You can set up proportions to find the width of the stream.

6/7.5=x/28

Cross multiply and solve for x.

168=7.5x

Divide by 7.5

x=22.4 ft

The stream is 22.4 ft wide
