Answer 1

2.Calculati:

a)

${2}^{5} + {6}^{3} = 2 \times 2 \times 2 \times 2 \times 2 + 6 \times 6 \times 6 = 32 + 216 =248$

b)

${5}^{2} - {3}^{2} = 5 \times 5 - 3 \times 3 = 25 - 9 = 16$

c)

${2}^{3} + {2}^{4} + {2}^{1} = 2 \times 2 \times 2 + 2 \times 2 \times 2 \times 2 + 2 \times 1 = 8 + 16 + 2 = 26.$

d)

${14}^{2} - {10}^{2} - {8}^{2} = 14 \times 14 - 10 \times 10 - 8 \times 8 = 196 - 100 - 64 = 32$

e)

${2}^{5} - {2}^{3} + {9}^{0} = 2 \times 2 \times 2 \times 2 \times 2 - 2 \times 2 \times 2 + 9 \times 0 = 32 - 8 + 1 = 25$

f)

${7}^{3} - {14}^{2} - {7}^{1} = 7 \times 7 \times 7 - 14 \times 14 - 7 \times 1 = 343 - 196 - 7 = 140$

g)

${5}^{0} + {5}^{1} + {5}^{2} = 5 \times 0 + 5 \times 1 + 5 \times 5 = 1 + 5 + 25 = 31$

h)

${4}^{3} - {3}^{3} + {5}^{0} = 4 \times 4 \times 4 - 3 \times 3 \times 3 + 5 \times 0 = 64 - 27 + 1 = 38$

i)

${2}^{3} + {5}^{3} + 2 \times 3 = 2 \times 2 \times 2 + 5 \times 5 \times 5 + 2 \times 3 = 8 + 125 + 6 =$
