Question

CALCULATI:1)RADICAL DIN 5²×7²×11²=

2)RADICAL DIN 2⁸×3⁴×13²

3)RADICAL DIN 13²×7² supra 15²


4)5²+12² supra 25²-15²=


​

Answer 1

1)

$\sqrt{ {5}^{2} \times {7}^{2} \times {11}^{2} } = 5 \times 7 \times 11 = 385$

2)

$\sqrt{ {2}^{8} \times {3}^{4} \times {13}^{2} } = {2}^{4} \times {3}^{2} \times 13 = 1872$

3)

$\sqrt{ \frac{ {13}^{2} \times {7}^{2} }{ {15}^{2} } } = \frac{13 \times 7}{15} = \frac{91}{15}$

4)

$\frac{ {5}^{2} + {12}^{2} }{ {25}^{2} - {15}^{2} } = \frac{25 + 144}{625 - 225} = \frac{169}{400}$

Answer 2

1) 5×7×11=35×11=385

2)2⁴×3²×13 = 16×9×13=1872

3)13×7supra15 = 91 supra 15

4) 25+144supra 625-225 =169+400=569
