Question

Помогите по алгебре пожалуйста

Answer 1

а)
$sqrt{25 times 81} = sqrt{25} times sqrt{81} = 5 times 9 = 45$

б)
$sqrt{0.49 times 16} = sqrt{0.49} times sqrt{16} = 0.7 times 4 = 2.8$

в)
$sqrt{400 times 2.25} = sqrt{400} times sqrt{2.25} = 20 times 1.5 = 30$

г)
$sqrt{ frac{9}{64} } = frac{3}{8} = 0.375$

д)
$sqrt{3 frac{6}{25} } = sqrt{ frac{81}{25} } = frac{9}{5} = 1.8$

е)
$sqrt{2 frac{46}{49} } = sqrt{ frac{144}{49} } = frac{12}{7} = 1 frac{5}{7}$

Answer 2

a)|25*81= 5*9=45
б) |0,49*16=0,7*4=2,8
в) |400*2,25=|900=30
г) |9/64=3/8
д) |81/25=9/5
е) |144/49= 12/7
