A) 2³x5+3²=
B) 700+070-1
C) 3x71-4x50
D) 34-24:8-3x4
E)5²+3x²-4
F) 5x2²+3-8
G) 5²-3x2²-1
H) 16:2-1+7²

Answer 1

Boa noite.

$A) 2^3x5+3^2= 8 . 5 + 9 = 40 + 9 = 49$

$B) 700+070-1 = 770 - 1 = 769$

$C) 3x71-4x50 = 213 - 200 = 13$

$D) 34-24:8-3x4 = 34 - 3 - 12 = 34 - 15 = 19$

$E)5^2+3^2-4= 25 + 9 - 4 = 34 - 4 = 30$

$F) 5x2^2+3-8 = 5 . 4 + 3 - 8 = 20 + 3 - 8 = 23 - 8 = 15$

$G) 5^2-3x2^2-1 = 25 - 3 . 4 - 1 = 25 - 12 - 1 = 25 - 13 = 12$

$H) 16:2-1+7^2 = 8 - 1 + 49 = 57 - 1 = 56$

Bons estudos! :-)
