There were 3 friends. Each of them bought 6 packs of candy. Each pack had 18 pieces of candy. How much candy did they have in total? .

3 × 6 = 18

18 × 18 = 324

SO, they had 324 pieces of candy in total.

Hope I helped:P

You have 3 friends each get 53 sweets. how many sweets do you give out?

estimate: 53 rounded is 50 so 50 ×3= 150

real answer: 53×3=159

you know this makes sense as both answers are near or less similar.

hope I helped

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