simplify the expression.
√(36x2/y7)
show your work.
note: do not leave a square root sign (symbol) in the denominator to fully simplify. also note, that the 7 is an exponent. 25 is in the numerator.

Step-by-step explanation:

You are expected to factor out all of the squares. The expression under the radical can be multiplied by (y/y) in order to make the denominator a square.*

_____

* This is the general approach you use to "rationalize the denominator" of radical expressions. You multiply under the radical by 1 in the form of a suitable fraction so that the root of the denominator contains no radicals. (For square roots, you want the denominator to be a perfect square; for cube roots, you want the denominator to be a perfect cube, and so on.)

step-by-step explanation:

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
