Question

10 задание помогите пожалуйста

Answer 1

x²-16=0
x²=16
x=4 или х=-4

х²=19
х=√19

√х+18=10
х+18=100
х=100-18
х=82


$frac{4x-3}{ sqrt{4x-3} }=0 \ frac{(4x-3)(sqrt{4x-3})}{ (sqrt{4x-3})(sqrt{4x-3}) }=0 \ frac{(4x-3)(sqrt{4x-3})}{ 4x-3 }=0 \ sqrt{4x-3}=0 \ 4x-3=0 \ 4x=3 \ x=0.75$

(√х)⁴=13
х²=13
х=√13

$sqrt{4x-3} *( x^{2} -11)=0 \ (4x-3)( x^{2} -11)^{2}=0 \ left { {{4x-3=0} atop {x^{2} -11=0}} right. \ left { {{4x=3} atop {x^{2} =11}} right. \ left { {{x=0.75} atop {x = sqrt{11} }} right.$
