Please help

$1.25=b^5\\ \sqrt[5]{1.25}=\sqrt[5]{b^5} \\ \sqrt[5]{1.0456395525912732^5}=\sqrt[5]{b^5} \\ 1.0456395525912732^{\frac55}=b^{\frac55}\\ 1.0456395525912732=b \\ $

If you can't see the image, b=1.04564

You guys do realize this is a calculator website you could literally put in 1.25=b^5 and it would give you an answer in seconds
