Use the property of logarithms to evaluate the expression. no decimals.

If you want to solve for x, then the answer is x = 6*sqrt(2) where "sqrt" is shorthand for "square root"

Explanation:

All logs below are base 4

log(5) - log(18) = log(20) - 2*log(x)

log(5) - log(18) = log(20) - log(x^2)

log(5/18) = log(20/x^2)

5/18 = 20/x^2 ... raise both sides as exponents (base = 4); logs cancel

5x^2 = 18*20 ... cross multiply

5x^2 = 360

x^2 = 360/5 ... divide both sides by 5

x^2 = 72

x = sqrt(72) ... see note below.

x = sqrt(36*2)

x = sqrt(36)*sqrt(2)

x = 6*sqrt(2)

note: we only consider the positive solution for x because x cannot be negative. We cannot input negative x values into log(x). The domain of log(x) is x > 0. So we don't consider "plus/minus" for the square root.

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
