simplify log_{1/3}(4)

Solution

simplify

lo g_{\frac{1}{3}} (4)

Solution

- 2 lo g_{3} (2)

+1

Decimal Notation

- 1.26185 \dots

Solution steps

lo g_{\frac{1}{3}} (4)

Apply log rule:

lo g_{\frac{1}{a}} (x) = - lo g_{a} (x)

lo g_{\frac{1}{3}} (4) = - lo g_{3} (4)

= - lo g_{3} (4)

Factor the number:

4 = 2^{2}

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

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x), x > 0

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

= - 2 lo g_{3} (2)
