Answer:

-i

i to the first power is itself

i to the second power is -1

i to the third power is -i

Then, i to the fourth power is 1, so it all repeats again.

A triangular frame has sides that measure 15'-7",20'-4" and 26'-2". What is the total length of three sides?
tatuchka [14]

we know that

1\ foot=12\ inches

1'=12"

<u>Part 1) </u>

we know that

side 1=15'-7"

side 2=20'-4"

side 3=26'-2"

To find the total length of three sides sum the three sides

so

total length=side 1+side 2 +side 3

substitute

total length=15'-7"+20'-4"+26'-2"

total length=(15'+20'+26')+(7"+4"+2")

total length=(61')+(13")

remember that

12"=1'

13"=12"+1"=1'+1"

substitute

total length=(61')+(1'+1")

total length=(62')+(1")---------> 62'-1"

therefore

<u>the answer is</u>

the total length of three sides is 62'-1"
