9 la puterea a 10=
27 la puterea a 7

Answer 1

27=3³; 81=3⁴; 9=3²; 1=3 la puterea 0; 9 la a 10= (3²)la a 10= 3 la puterea 20 27 la puterea 7 =( 3³)la a 7= 3²¹

Answer 2

$27=3 \cdot 9=3 \cdot 3^2=3^{1+2}=3^3 \\ 81=9 \cdot 9=3^ 2 \cdot 3^2=3^{2+2}=3^4 \\ 9=3 \cdot 3=3^{1+1}=3^2 \\ 1=3^0 \\ 9^1^0=(3^2)^1^0=3^2^0 \\ 27^7=(3^3)^7=3^2^1$
