Question

if a=2
26=-2 , find the value of
of (2a²6-2a62 +963)​

Answer 1

How to solve for exponents

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.
