Question

2x^8.7 =100 how to solve it

Answer 1

Answer:-

$= > x = \sqrt[87]{50 {}^{10} }$

Step by step explanation


$2x {}^{8.7} = 100$
Divide both sides of the equation by 2

$= > x {}^{8.7} = 50$
$using \: \: a {}^{ \frac{m}{n} } = \sqrt[n]{a {}^{m} } , \: transform \: \: the \\ \: \: expression$

$= > \sqrt[10]{x {}^{87} } = 50$
Raise both sides of the equation to the power of 10

$= > x {}^{87} = 50 {}^{10}$
Take the root of both sides of the equation

$= > x = \sqrt[87]{50 {}^{10} }$
