simplify (2(2.1)+1)/(log_{2)(2.1)}

simplify

\frac{2 ( 2.1 ) + 1}{lo g _{2} ( 2.1 )}

\frac{26}{5 ( lo g _{2} ( 21 ) - 1 - lo g _{2} ( 5 ) )}

Decimal Notation

4.85804 \dots

Solution steps

\frac{2 ( 2.1 ) + 1}{lo g _{2} ( 2.1 )}

Apply rule:

(a) = a

(2.1) = 2.1

= \frac{2 \cdot 2.1 + 1}{lo g _{2} ( 2.1 )}

2 \cdot 2.1 + 1 = 5.2

= \frac{5.2}{lo g _{2} ( 2.1 )}

lo g_{2} (2.1) = lo g_{2} (21) - 1 - lo g_{2} (5)

= \frac{5.2}{lo g _{2} ( 21 ) - 1 - lo g _{2} ( 5 )}

\frac{5.2}{lo g _{2} ( 21 ) - 1 - lo g _{2} ( 5 )} = \frac{52}{10 ( lo g _{2} ( 21 ) - 1 - lo g _{2} ( 5 ) )}

= \frac{52}{10 ( lo g _{2} ( 21 ) - 1 - lo g _{2} ( 5 ) )}

Cancel

= \frac{26}{5 ( lo g _{2} ( 21 ) - 1 - lo g _{2} ( 5 ) )}
