Answer: 2 bananas * 2 bananas = 4 bananas^2 (4 bananas squared)

2 bananas squared = 4 bananas
4 bananas squared = 16 bananas

no , it equals 4 bananas
ie..

2 x 2 = 4

bananas x bananas = bananas

therefore 4 bananas

4^2 = 16
4 squared = 16

4 bananas squared = 4 bananas x 4 bananas = 16 bananas

put 4 in your calculator and then hit the x^2 button

when measuring the square footage of your room...

20 ft x 20 ft = 400 sq ft
not 400 sq ft^2
400 sq ft^2 = 160000 sq ft

you can also say 20 ft squared = 400 sq ft
or 20 ft^2 = 400 sq ft
but 20 sq ft isnt 400 sq ft either

so
(4 bananas squared)
isnt 4 bananas
its 16 bananas

think of each x as a banana

xxxx
xxxx
xxxx
xxxx

the x's form a square

4 bananas x 4 bananas = 16 bananas

not 16^2 or 16 bananas squared

or you can count the x's below
in the 20 x^2 room

1 N * 1 s = 1 Ns


1 newton is 1 second!
time is built into newtons

if someone tells me I only have a force of 80N

I know what I can do with it without thinking , about time.

80N will accelerate a 80 kg mass to 1 m/s/s in 1 second.
or
80N will will accelerate a 1 kg mass to 80 m/s/s in 1 second
or
80N will accelerate a 100 kg mass to .8 m/s/s in 1 second

so notice in the 3 examples above the only things that remained the same is

80N will accelerate a
and
in 1 second

1 newton is the force required to accelerate 1kg to 1 m/s/s

in physics we use N as the units of force
and
we use Ns as the units of momentum

momentum is not force
and
force is not momentum
from wiki force and momentum

In classical mechanics, momentum (pl. momenta; SI unit kg·m/s, or, equivalently, N·s)

The SI unit of force is the newton (symbol N), which is the force required to accelerate a one kilogram mass at a rate of one meter per second squared
