Simplify: log base 3 (1/3) ...?

yarga [219]

The answer is 1.

$log_3( \frac{1}{3} )$
_____
Since $log_y(x) = \frac{log_{10}(x)}{log_{10}(y)}$ , then: $log_3( \frac{1}{3} )= \frac{log_{10} ( \frac{1}{3}) }{log_{10}(3)}$
_____
Since $\frac{1}{x} = x^{-1}$ , then: $\frac{log_{10} ( \frac{1}{3}) }{log_{10}(3)} = \frac{log_{10}(3^{-1} )}{log_{10}(3)}$
_____
Since $log x^{a} =a*logx$ , then: $\frac{log_{10}(3^{-1} )}{log_{10}(3)}= \frac{-1*log_{10}(3)}{log_{10}(3)}$

From here: $\frac{-1*log_{10}(3)}{log_{10}(3)}=-1*\frac{log_{10}(3)}{log_{10}(3)}=-1*1 = -1$

Can some help me with this problem please -41=-2/5(45n+60)+n

liq [111]

Answer:

Step-by-step explanation:

I will ASSUME you mean

-41 = (-2/5)(45n + 60) + n

and not -41 = -2/(5(45n + 60)) + n

or -41 = -2/(5(45n + 60) + n)

-41 = (-2/5)(45n + 60) + n

distribute the (-2/5)

-41 = -18n - 24 + n

combine like terms

17n = 17

reduce to simplest form

n = 1
