Question

Efectuați calculele:
a)2 la puterea a2+2 la puterea a 4+2 la puterea 0
b)4 la puterea 3-7 la puterea 0
c)121 la puterea 0:1 la puterea 121
d)(7 -5)la puterea a 2:4

Answer 1

$a)2^{2}+2^{4}+2^{0}=4+16+1=21 \\ \\b) 4^{3}-7^{0}=64-1=63 \\ \\ c)121^{0}: 1^{121} =1:1=1 \\ \\d) (7-5)^{2}:4=2^{2}:2^{2}=1$
