jhonyy9 (jhonyy9):
or
a^2 *a^3 = a^(2+3) = a^5
jhonyy9 (jhonyy9):
do you understand it ?
OpenStudy (anonymous):
so would it b 8x5
jhonyy9 (jhonyy9):
why 8 ?
OpenStudy (anonymous):

jhonyy9 (jhonyy9):
why 15
so 5^3 = 5*5*5 =
OpenStudy (anonymous):
25
OpenStudy (anonymous):
@jhonyy9 im confused
jhonyy9 (jhonyy9):
so than us this
a^2 * b^2 = (a*b)^2
OpenStudy (anonymous):
or is 125 x 27

jhonyy9 (jhonyy9):
so i have wrote there that 5^3 = 5*5^2
and there is again 3^2 so
5*5^2 *3^2 = 5*(5*3)^2 = 5*15^2 =
jhonyy9 (jhonyy9):
can you calculi it now ?
jhonyy9 (jhonyy9):
15^2 =15*15 = 225
5*15^2 =5*225=
OpenStudy (anonymous):
1125
jhonyy9 (jhonyy9):
yes but do you understand it now how can you simplifie it and calculi easy ?

i think so, 125 x 27 is tht right
OpenStudy (anonymous):
3375
jhonyy9 (jhonyy9):
how you have got 27 ?
jhonyy9 (jhonyy9):
because 3^2 =3*3
or not ?
jhonyy9 (jhonyy9):
