OpenStudy (anonymous):

help simplify

OpenStudy (saifoo.khan):

\[\Huge -3 \times 180^\frac42 \times h^\frac42\]

OpenStudy (anonymous):

what do i do now

OpenStudy (anonymous):

\[-3\sqrt{h ^{2}h ^{2}*4*5*9}\]

OpenStudy (anonymous):

-3hsqrt90

OpenStudy (saifoo.khan):

cancel terms, \[\Large -3 \times 180^2 h^2\] you can use a calc now. ;)

OpenStudy (anonymous):

-3 is the number that will be part of the answer

OpenStudy (anonymous):

@saifoo.khan

OpenStudy (saifoo.khan):

-3 and 180^2 are co-efficents so they can be multiplied and it will give you another co-efficent.

OpenStudy (anonymous):

-18

OpenStudy (anonymous):

@saifoo.khan will it give me 18

OpenStudy (saifoo.khan):

\[-3 \times 18 \times 18 = ?\]

OpenStudy (anonymous):

-972

OpenStudy (saifoo.khan):

Right. so now you get, \[\large -972 h^2\]

OpenStudy (anonymous):
