Mehek (mehek14):
I said the exponents.
OpenStudy (acespeedfighter):
5.75*2=
OpenStudy (acespeedfighter):
10 is 20 and 1/2^4 is 2
Mehek (mehek14):
. . .
Here let me break it down for you.

OpenStudy (acespeedfighter):

Mehek (mehek14):

Mehek (mehek14):
Hold on
You messed up the exponent
Mehek (mehek14):
It's \(\bf \dfrac{1}{2}*\dfrac{1}{2}*\dfrac{1}{2}*\dfrac{1}{2}=\dfrac{1}{16}\)
Mehek (mehek14):
\(\bf 3 + 25 * \dfrac{1}{16}\)
Multiply first then add.
OpenStudy (acespeedfighter):
25 1/16?
Mehek (mehek14):
Multiply
\(\bf 25 * \dfrac{1}{16}\)
