Question

Say I had a question like pi^x=5.4 and I wanted to find x. How would I go about this algebraically?

Answer 1

ln(pi^x)=ln(5.4)
xln(pi)=ln(5.4)
x=ln(pi)/ln(5.4)

Answer 2

Ok but is there an easy way to do ln(pi)/ln(5.4)=x without a calculator?

Answer 3

@lalaly
when you divide ln(pi)??? to get x
xln(pi)=ln(5.4)
x=ln(pi)/ln(5.4)

Answer 4

sorry x=ln(5.4)/ln(pi)
