Please use " ^ " to indicate exponentiaton:   <span>Use the equation

350 = (270)(1.05)^x.  
Take the log of both sides:

log 350 = log 270 + x*log 1.05.

Subtr. log 270 from both sides:

log 350 - log 270 = x*log 1.05
                               log 350 - log 270
Sove for x:      x = -------------------------
                                  log 1.05
                                                           2.544- 2.431
Evaluate this using a calculator.  x = ------------------
                                                                0.0212

x is then approx. 5.33, or 5 1/3 years.

Anon25 [30]

Answer:

They either both have to be positive or negative.

Step-by-step explanation:

1 / 1 = 1

-1 / -1 = 1

This gets you positive, when both dividend and divisors are positive or negative.

-1 / 1 = -1

1 / -1 = -1

This gets you negative, when both dividend and divisors are different signs.
