Question

mim ajudem a responde não consigo fazer

Answer 1

a)7×2³ - 2³×5=7×8 -8×5= 56-40=16

b) √16 ×3²- 6²÷√9 = 4× 9 - 36÷ 3= 36-12= 24

c)11²-(68+7²)= 121-68-49=4

d)√25 × (√196 -2³)= 5 × (14-8)=5× 6=30

e)(2³×3²-6²)÷[18÷(15-3×2²)]²= (8×9-36) ÷[18÷(15-3×4)]²= 72 ÷ [18÷(15-12)]²=72÷ (18÷3)²=72÷6²=72÷36=2
