Answer 1

Answer:

$1)343=7×7×7=7³ \\ </p><p>2)3²=3×3=9 \\ </p><p>2³=2×2×2=8 \\ </p><p>Therefore, \: 3² \: is \: greater. \\ </p><p>4) \frac{ {3}^{5} }{ {3}^{2} } \times {3}^{10} \\ = \frac{3 \times 3 \times 3 \times 3 \times 3}{3 \times 3} \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \\ = 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \times 3 \\ = {3}^{13} \\ 5)i) {10}^{3} \times {9}^{0} + {3}^{3} \times 2 + {7}^{0} \\ = {10}^{3} \times 1 + {3}^{3} \times 2 + 1 \\ = 1000 + 27 \times 2 + 1 \\ = 1000 + 54 + 1 \\ = 1055 \\ ii) {6}^{3 } \times {7}^{0} + {( - 3)}^{4} - {9}^{0} \\ = {6}^{3} \times 1 + {( - 3)}^{4} - 1 \\ = 216 + 81 - 1 \\ = 297 - 1 \\ = 296$

Answer 2

Answer:

$7 {}^{343}$

$3 {}^{2} or \: 2 {}^{3} \: = \: 3 \times 1 = 3 \: \\ = 3 \times 3 = 9 \\ = 2 \times 1 = 2 \\ = 2 \times 2 = 4 \\ = 4 \times 2 = 8 \: \\ so \: 3 {}^{2} is \: greatest$
