Question

Calculati: radical din 2 la a doua ori 3 la a doua ori 5 la a doua
va rog ajutati-ma!!!

Answer 1

  _______

√(2²×3²x5²) = 2 × 3 × 5 = 30

√2² × √3² x √5² = 2 × 3 × 5 = 30

Answer 2

$1) \sqrt{( {2}^{2} \times {3}^{2} \times {5}^{2} } = \sqrt{4 \times 9 \times 25} = \sqrt{900} = 30 \\ \\ 2) \sqrt{2} ^{2} \times { \sqrt{3} }^{2} \times { \sqrt{5} }^{2} = \sqrt{2 ^{2} } \times \sqrt{ {3}^{2} } \times \sqrt{ {5}^{2} } = 2 \times 3 \times 5 = 6 \times 5 = 30$
