What is the simplified form of the following expression?

OpenStudy (anonymous):

depends on the expression

OpenStudy (anonymous):

13[6^2/(5^2-4^2)+9]

OpenStudy (superdavesuper):

since everything is given, the simplest form will be whatever value the expression calculates to be :)

OpenStudy (anonymous):

Well what do the brackets mean? Are they just like parenthesis? Like would I solve the exponents first still or would I distribute the 13?

OpenStudy (anonymous):

the brackets mean that after the ( ) then you solve what is in the brackets

OpenStudy (anonymous):

what is 5^2 and what is 4^2 then add them together

OpenStudy (anonymous):

So like 36/25-16+9 36/9+9 4+9 13 is what is in the brackets.

OpenStudy (anonymous):

So my answer is 169?

OpenStudy (anonymous):

5^2 is not 25 it is 100 when you have a ^number you mult. it by it self that many times

OpenStudy (anonymous):

Yeah 5*5=25

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (superdavesuper):
