Question

Help me with this interesting and challenging question. I need smart people!

Answer 1

Express the following expression as a single base to the exponent.

Answer 2

\[\frac{ 15 }{ 2^{-5}+2^{-6}+2^{-7}+2^{-8}}\]

Answer 3

Please someone... this is an extra credit question that I need help on.

Answer 4

take \(2^{-4}\) common from denominator
and then try to simplify

Answer 5

What the hell does that mean

Answer 6

i mean like
this is ur denominator part->

\(2^{-5}+2^{-6}+2^{-7}+2^{-8}\)

you can write it like this-

\(2^{-4} \left(2^{-1}+2^{-2}+2^{-3}+2^{-4} \right)\)

\(2^{-4} \left(\Large\frac{1}{2}+\frac{1}{4}+\frac{1}{8}+\frac{1}{16}\right)\)

now simplify the thing inside the brackets and then put this value of denominator into the original expression and then simplify

Answer 7

OMG, so the answer is just 1!!

Answer 8

\[\frac{ 15 }{ 2^{-5}+2^{-6}+2^{-7}+2^{-8}} = \dfrac{2^8*15}{2^3+2^2+2^1+2^0} = ?\]

Answer 9

Rational, how is that possible??

Answer 10

See anything wrong above ?
