Answer 1

momentan nu am un caiet la îndemână,dar dacă nu înțelegi îți explic

x=(√3/2)³•(5/√63-√18/√350):(3√7/4)la -1

(√3/2)³=>(√3)³=√3•√3•√3=3•√3=3√3

=> 2³=2•2•2=4•2=8

=> 3√3/8

√63=3√7

√18=3√2

√350=5√14

x = 3√3/8•(5/3√7-3√2/5√14(rationalizam):3√7/4 la -1

x=3√3/8•(5√7/21-3√28/5•14):3√7)4 la -1

x = 3√3/8•(5√7/21-3•2√7/70):3√7 la -1

x = 3√3/8•(5√7/21-6√7/70):3√7 la -1

x=(3√3/8•5√7/21-3√3/8•6√7/70):3√7 la -1

x=(15√21/168-18√21/560)(simplificam):3√7 la -1

x=(5√21/56(amplificam cu 5)-9√21/280):(1/3√7)¹

x = (25√21-9√21/280):(√7/3•7)

x=16√21/280(simplificam):√7/21

x=8√21/140:√7/21

x=4√21/70•21/√7

x=2√21/35•21√7/7

x=2√21/35•3√7

x=6√147/35
