f) 3²-2²=
me ajude por favor ​

Answer 1

a) $3^2=3 \times 3=9$

b) $9^3=9 \times 9 \times 9=729$

c) $3^3-3^2=3 \times 3 \times 3-3 \times 3=729-9=720$

d) $4^2-2^4=4 \times 4-2 \times 2 \times 2 \times 2=16-16=0$

e) $7^2-6^2=7 \times 7-6 \times 6=13$

f) $3^2-2^2=3 \times 3-2 \times 2=9-4=5$

Answer 2

Resposta:

A) 3²= 3×3= 9

B) 9³= 729

C) 3³-3²= (3.3.3)-(3.3)= 27-9= 18

D) 4²-2⁴= (4.4)-(2.2.2.2)= 16-16= 0

E) 7²-6²= (7.7)-(6.6)=49-36= 13

F) 3²-2²=(3.3)-(2.2)= 9-4= 5

Espero ter ajudado!❤️
