Question

I don't understand where it says "enter your answer correct to four decimals" I've tried 20 different answers and I just can't find it

Answer 1

4^.2X +6 = 43
4^.2X = 37
Taking logs of both sides
X * log (4.2) = log (43)
X = log (43) / log (4.2)
X = 1.633468456 / 0.6232492904
X = 2.6208910001
rounded to 4 decimal places:
X = 2.6209
