Question

va rog este urgent! dau 5 stele ​

Answer 1

Simbolul "^" înseamnă "ridicat la puterea" (ex. 3^2 = 3 ridicat la puterea doua).

a) 2^5 + 6³ = 32 + 216 = 248

b) 5² - 3² = 25 - 9 = 16

c) 2³ + 2^4 + 2^1 = 8 + 16 + 2 = 26

d) 14² - 10² - 8² = 196 - 100 -64 = 32

e) 2^5 - 2³ + 9^0 = 32 - 8 + 1 = 25

f) 7³ - 14² - 7^1 = 343 - 196 - 7 = 140

g) 5^0 + 5^1 + 5^2 = 1+5+25 = 31

h) 4^3 - 3^3 +5^0 = 64-27+1 = 38

i) 2^3 + 5^3 + 2·3 = 8 + 125 + 6 = 139

Answer 2

a)

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

b)

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

c)

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

d)

$14 {}^{2} - {10}^{2} - {8}^{2} = 196 - 100 - 48 = 48$

e)

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

f)

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

g)

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

h)

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

i )

${2}^{3} + {5}^{3} + 2 \times 3 = 8 + 125 + 6 = 139$

Aștept stelele...
