simplify-0.7*log_{2}(0.7)-0.3log_{2}(0.3)

simplify

- 0.7 \cdot lo g_{2} (0.7) - 0.3 lo g_{2} (0.3)

- lo g_{2} (\frac{3 ^{0.3} \cdot 7 ^{0.7}}{5}) + 1

Decimal Notation

0.88129 \dots

Solution steps

- 0.7 lo g_{2} (0.7) - 0.3 lo g_{2} (0.3)

- 0.7 lo g_{2} (0.7) = - 0.7 lo g_{2} (\frac{7}{10})

0.3 = \frac{3}{10}

= - 0.7 lo g_{2} (\frac{7}{10}) - 0.3 lo g_{2} (\frac{3}{10})

- 0.7 lo g_{2} (\frac{7}{10}) = - lo g_{2} ((\frac{7}{10})^{0.7})

- 0.3 lo g_{2} (\frac{3}{10}) = - lo g_{2} ((\frac{3}{10})^{0.3})

= - lo g_{2} ((\frac{7}{10})^{0.7}) - lo g_{2} ((\frac{3}{10})^{0.3})

Apply log rule:

lo g_{a} (x) + lo g_{a} (y) = lo g_{a} (x y)

- lo g_{2} ((\frac{3}{10})^{0.3}) - lo g_{2} ((\frac{7}{10})^{0.7}) = lo g_{2} ((\frac{3}{10})^{0.3} (\frac{7}{10})^{0.7})

= - lo g_{2} ((\frac{3}{10})^{0.3} (\frac{7}{10})^{0.7})

Simplify

(\frac{3}{10})^{0.3} (\frac{7}{10})^{0.7} : \frac{3 ^{0.3} \cdot 7 ^{0.7}}{10}

= - lo g_{2} (\frac{3 ^{0.3} \cdot 7 ^{0.7}}{10})

Apply log rule:

lo g_{a} (\frac{x}{y}) = lo g_{a} (x) - lo g_{a} (y)

lo g_{2} (\frac{3 ^{0.3} \cdot 7 ^{0.7}}{10}) = lo g_{2} (3^{0.3} \cdot 7^{0.7}) - lo g_{2} (10)

= - (lo g_{2} (3^{0.3} \cdot 7^{0.7}) - lo g_{2} (10))

lo g_{2} (3^{0.3} \cdot 7^{0.7}) = 0.3 lo g_{2} (3) + 0.7 lo g_{2} (7)

= - ((0.3 lo g_{2} (3) + 0.7 lo g_{2} (7)) - lo g_{2} (10))

Apply rule:

(a) = a

(0.3 lo g_{2} (3) + 0.7 lo g_{2} (7)) = 0.3 lo g_{2} (3) + 0.7 lo g_{2} (7)

= - (0.3 lo g_{2} (3) + 0.7 lo g_{2} (7) - lo g_{2} (10))

lo g_{2} (10) = 1 + lo g_{2} (5)

= - (0.3 lo g_{2} (3) + 0.7 lo g_{2} (7) - (1 + lo g_{2} (5)))

Apply the distributive law:

- (a + b) = - a - b

- (1 + lo g_{2} (5)) = - 1 - lo g_{2} (5)

= - (0.3 lo g_{2} (3) + 0.7 lo g_{2} (7) - 1 - lo g_{2} (5))

0.3 lo g_{2} (3) = lo g_{2} (3^{0.3})

0.7 lo g_{2} (7) = lo g_{2} (7^{0.7})

= - (lo g_{2} (3^{0.3}) + lo g_{2} (7^{0.7}) - 1 - lo g_{2} (5))

lo g_{2} (3^{0.3}) + lo g_{2} (7^{0.7}) - lo g_{2} (5) = lo g_{2} (\frac{3 ^{0.3} \cdot 7 ^{0.7}}{5})

= - (lo g_{2} (\frac{3 ^{0.3} \cdot 7 ^{0.7}}{5}) - 1)

Apply the distributive law:

- (a - b) = - a + b

- (lo g_{2} (\frac{3 ^{0.3} \cdot 7 ^{0.7}}{5}) - 1) = - lo g_{2} (\frac{3 ^{0.3} \cdot 7 ^{0.7}}{5}) + 1

= - lo g_{2} (\frac{3 ^{0.3} \cdot 7 ^{0.7}}{5}) + 1

ln (\frac{2.3}{1.5})
