Question

ex 14. Apasati pe imagine

Answer 1

N=(-2)^6*[-3+(15-4)]:2^8

N=2^6*(-3+11):2^8

N=2^6*8:2^8

N=2^6*2^3:2^8

N=2^9:2^8

N=2

Am utilizat urmatoarele reguli de calcul cu puteri:

1. a^m*a^n=a^(m+n)
2. a^m:a^n=a^(m-n).

Answer 2

${( - 2)}^{6} \times [- 3 + (15 - 4)] : {2}^{8} = \\ \\ {( - 2)}^{6} = 64 \\ \\ - 3 + 15 = 12 \\ \\ 64 \times 8 = 512 \\ \\ {2}^{8} = 56 \\ \\ 512 : 256 = 2$
