Question

please heelp me !!! can someone explain me how this fraction gets clean?

Answer 1

like using my calculator

Answer 2

what they have do is multiplied both sides by 32. This will remove the denominator of L...

to the equation is

\[L = \frac{88.36 \times 32}{4\pi^2}\]

Answer 3

now if you enter the above equation you should get the given answer

Answer 4

i entered exatcly like that but i got 6976.62

Answer 5

\[\frac{88.36}{4\pi^2}=\frac{L}{32}\]
\[32\times\frac{88.36}{4\pi^2}=L\]
\[8\times\frac{88.36}{\pi^2}=L\]
\[\frac{706.88}{\pi^2}=L\]
\[L\approx \frac{706.88}{9.8696}\]
\[=71.62195023101241\]
\[\approx 71.6\]

Answer 6

I think you need som brackets

\[L = \frac{(88.36 \times 32)}{( 4 \times \pi^2)}\]

and you should get the desired answer.
