Answer 1

Răspuns:

Explicație pas cu pas:

b)

$3^{10}*2^{10}-6^{11}:6 = (3*2)^{10} - 6^{11-1} = 6^{10} - 6^{10} =0$

c)

$(10^{33}:5^{33}:2^2)^5=\\\\=(\frac{10^{33}}{5^{33}}:2^2)^5=\\\\=[(\frac{10}{5})^{33}:2^2]^5=\\\\=[(\frac{10}{5})^{33}:2^2]^5=\\\\=(2^{33}:2^2)^5=\\\\=(2^{33-2})^5=\\\\=(2^{31})^5=\\\\=2^{31*5}=\\\\=2^{155}$
