In this case, base 6: Now we can use a property of logarithms, , to move the exponent of the argument out in front. Being able to use this property to get the variable out of the exponent is the whole reason we use logarithms on equations where the variable is in an exponent.

SOLUTION: 8(3^6-x)=40 What is the easiest way to solve for X. Algebra -> Exponential-and-logarithmic-functions -> SOLUTION: 8(3^6-x)=40 What is the easiest way to solve for X. Log On Algebra: Exponent and logarithm as functions of power Section

x*(x-1) is right. Use the ^ (caret) for exponentiation. x^2 means x squared. x/2y means Use the ^ (caret) for exponentiation. x^2 means x squared. x/2y means Resources : Simplifier Portal , help with entering simplifier formulas (a must read).

Given a normal distribution with µ = 40 and σ = 6, find a.) the area below 32; b.) the area above 27; c.) the area between 42 and 51; d.) the x value that has 45% of the area below it. e.) The x value that has13% the area above it. Answer by ewatrrr(24785) (Show Source):

40% less means 100-40 =60% let the number be x now the eqaution becomes 60%of x=40 60/100*x=40 6x/10=40 6x ...

You can put this solution on YOUR website! forty liters of a 60% salt soltution are reduced to a 45% SOLUTION. hOw much must be drained off and replaced with distilled water so that the resulting solution will contain only 45% salt?

Question 1055176: Use the normal approximation to the binomial to find the probability for the specific value of X. n=30 p=0.5 X=18 Answer by ewatrrr(24785) ( Show Source ):

If a 7 minute call costs $10, and a 4 minute call costs $6.40, find each rate. Seven minute call let the first minute cost be x balance will be 10-x for the balance 6 minutes rate /minute = 10-x / 6 SFour minute call let the first minute cost be x balance will be 6.4 -x for the balance 3 minutes rate /minute = 6.4-x / 3 10-x / 6 =6.4-x / 3
