Question

x^3.5=46.74 solve of x

Answer 1

use logs

ln(x^3.5) = ln(46.74)

applying log laws

\[3.5\ln(x) = \ln(46.74)\]

divide both sides by 3.5

evaluate the right hand side

the raise each side as a power of e for the solution.

Answer 2

\[2^{2} = 4...............\sqrt{4} = 2\]

same way
\[\sqrt[3.5]{46.74} = 2.99\]

so x = 2.99
