\(42 + (x-3)^2 -- 28 \)
Right?
OpenStudy (anonymous):
Put \(x = 6\)
OpenStudy (anonymous):
\(42 + (6-3)^2 -- \ 28\)
OpenStudy (anonymous):
What is \(6-3\) = ??

its 3
OpenStudy (anonymous):
\(42 + (3)^2 -- \ 28\)
OpenStudy (anonymous):
what is \(3^2\) = ??
OpenStudy (anonymous):
6

\(3 \times 2 = 6\)
\(3^2 = 3 \times 3 = ??\)

Power means to multiply the number that many times like:
\(4^3\), it means to multiply \(4\), \(3\) times, ie \(= 4 \times 4\times 4 = 64\)
OpenStudy (anonymous):
oh okay i messed up my bad.
OpenStudy (anonymous):
So, \(3^2 = ??\)
OpenStudy (anonymous):
\(3^2\) means to multiply \(3\), \(2\) times ie \(= 3 \times 3 = ??\)

9 right?
OpenStudy (anonymous):
yep.
OpenStudy (anonymous):
\(42 + 9 - 28\)
OpenStudy (anonymous):
\(42+9 =??\)
OpenStudy (anonymous):
i dont think the question is asking for a power by stating (x-3)2, i think its asking basically (6)-3x2

Really?
OpenStudy (anonymous):
so solve the equation by substituting 6 for x and then see which symbol makes the statement true. if that makes sense :/
