Question

Calculati:
a)2√3 +3*4√3=
b)5√2 -2√2 *2=
c)√6*(3√5-2√5)-√2 *√15=
d)(4√2-√2)*√2 +√2* √18=
e)√3*(2√3+3√5)-√5*(√3+2√3)=
f)2*(√12-√3)+(√27-√48)*3=
va rog ajutati-ma dau coroana si mai multe puncte(sa fie calculate)

Answer 1

a) 2£(radical)3 +3×4£3
2£3+12£3=14£3
b) 5£2-2£2×2
5£2 -4£2=£2
c) £6 × (3£5-2£5)-£2×£15
£6×£5-£30
£30-£30=0
Sper că sunt bine

Answer 2

a) 2√3+3*4√3=2√3+12√3=14√3
b) 5√2-2√2*2= 5√2-4√2=√2
c) √6*(3√5-2√5)-√2*√15= (3√30-2√30)- √30= √30-√30=0
d) (4√2-√2)*√2+√2*√18=(4√4-√4)+√36=3√4+36=6+36=42
