What is the value of the exponential expression below ?

x^(1/2) means that you are taking the square root of some number. You can use this symbol on your calculator √ . So √16 is 4. The 1/2 in this case is a power.

Put it in your calculator this way.

√

16

=

It should come up as 4.

So the answer is A.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

the first one
