Question

$a - m = a 1 \m$
​

Answer 1

Step-by-step explanation:

$\begin{gathered}\sf m - \frac{1}{m} = 5 \\ \\ \sf squaring \:on\:both\:sides \\ \\ \sf { (m - \frac{1}{m})}^{2} = {5}^{2} \\ \\ \sf {m}^{2} - 2× m×\frac{1}{m} + \frac{1}{{m}^{2}} = 25 \\ \\ \sf {m}^{2} + \frac{1}{{m}^{2}} = 25 + 2 = 27 \\ \\ \sf Further \:squaring \:on\:both\:sides \\ \\ \sf { ( {m}^2 + \frac{1}{{m}^{2}} )}^{2} = {27}^{2} \\ \\ \sf {m}^{4} + 2 × {m}^{2} × \frac{1}{{m}^{2}} + \frac{1}{{m}^{2}} = 729 \\ \\ \sf {m}^{4} + 2 + \frac{1}{{m}^{4}} = 729 \\ \\ \sf {m}^{4} + \frac{1}{{m}^{4}} = 727 \end{gathered}$

$\begin{gathered}\begin{gathered}\begin{gathered}\small\boxed{ \begin{array}{cc}\large\sf \: {\underline{✰ More \: Formulae✰}} \\ \\ \bigstar \: \sf{Gain = S.P – C.P} \\ \\ \bigstar \:\sf{Loss = C.P – S.P} \\ \\ \bigstar \: \sf{S.P = \dfrac{100+Gain\%}{100} \times C.P} \\ \\ \bigstar \: \sf{ C.P =\dfrac{100}{100+Gain\%} \times S.P} \\ \\\bigstar \: \sf{ S.P = \dfrac{100-loss\%}{100} \times C.P} \\ \\ \bigstar \: \sf{ C.P =\dfrac{100}{100-loss\%} \times S.P}\end{array}}\end{gathered}\end{gathered}\end{gathered}$
