Question 538508: Is there some real number exponent such that 10^k = 75?
I figured that 10^7.5=75, is this correct, if so would this be considered a real number or otherwise?
The second part of this questions is how can I evaluate this through the use of a calculator. Would using the scientific notation be ideal

You can put this solution on YOUR website!
10^k = 75
log(10^k)=log(75)
k=log(75)
and it is real
there is a log button on scientific calculators
