sally will get it right this time We'll p stands

00:24

for parentheses so simplified inside the princes First let's do

00:29

that three times seven is twenty one and minus fifteen

00:34

and then that'll get us to end times quantity six

00:36

and squared well e stands for exponents so it's time

00:41

both terms inside the parentheses and that gets us to

00:45

in and then times twenty thirty six in squared r

00:48

m then stands for multi legation which is next multiplied

00:52

like terms from the previous step and we get to

00:56

times thirty six times and times and see where that

00:58

seventy two and cubed well we didn't get to the
