Let's break this statement into small pieces. Let's start with (-3)^{3}. This means -3 \times -3 \times -3 which is equal to -27 (-3 \times -3 = 9, 9 \times -3 = -27).

Note the following rules

  • - \times - = +
  • + \times + = +
  • - \times + = -
  • + \times - = -

Now let's solve the rest of the equation. -2 \cdot (-3)^{3} = -2 \cdot -27 (Note \cdot is the same as \times. = -2 \cdot -27, 54

The answer is 54

Given log4(3) =0.7925 and log4(5) =1.1610, use log properties to find log4(300).
Ede4ka [16]

Answer:

4.1145

Step-by-step explanation:

You can use the following formula to solve this kind of problems,

log_{a}(b)  +  log_{a}(c)  =  log_{a}(bc)

So, let's start of with log4_(300). Since the question have already gave log4_(3) =0.7925 and log4_(5) =1.1610. It means that you have to split the 300 into the simplest form where almost all of the numbers are 3 and 5.

log_{4}(300)  =  log_{4}(4 \times 5 \times 3 \times 5)  \\  =  log_{4}(4)  + log_{4}(5)  + log_{4}(3)  + log_{4}(5)  \\   = 1 + 1.1610 + 0.7925 + 1.1610 \\  = 4.1145
