Determining Wavelength of Most Intense Electromagnetic Radiation at 2500.1 °C

[XBOX999]

Homework Statement

Determine the wavelength of the most intense electromagnetic radiation
emitted from a furnace at 2500.1 °C.

Homework Equations

Wien Law Tλ max = 1/5 c2
where c2= 1.44 cmK
or another equation
λ=b/T where B= 2.897*10^-3 m.k

The Attempt at a Solution

when I solve it with equation 1:
I got 1.0388*10^-4 cm
when I solve it with the second equation
I got 1044.6 nm
Please check my answer if it write if the equations are write to solve the problem and check my significant digits.

Your answer(s) look good.
When you do the calculation

λ=c2 / 5T,​

How many significant figures are there in c2? And in T?
