Question

Sabendo que a= 3³ e b=27² quanto é:
a²
b : a
a . b
a : b
b²

Answer 1

a² =
${(3}^{3}) {}^{2} = {3}^{6} = 729$
b ÷ a =
${27}^{2} \div {3}^{3}$
$729 \div 27 = 27$
a . b=
${3}^{3} \times {27}^{2} =$
$27 \times 729 = 19.683$
a ÷ b:
${3}^{3} \div {27}^{2} =$
$27 \div 729 = 0.037037...$
b²=
$({27}^{2} ) {}^{2} =$
${729}^{2} = 531.441$
