Question

what are some rules to solve exponential equations?​

Answer 1

Step-by-step explanation:

solve an exponential equation, take the log of both sides, and solve for the variable. Ln(80) is the exact answer and x=4.38202663467 is an approximate answer because we have rounded the value of Ln(80).. Check: Check your answer in the original equation.

Answer 2

Answer:

xn=y. Take the log of both sides:

logxn=logy. By identity we get:

n⋅logx=logy. Dividing both sides by log x: n=logylogx. Find the exponent of a number. ...

3n=81. Take the log of both sides:

log3n=log81. By identity we get:

n⋅log3=log81. Dividing both sides by log 3: n=log81log3.
