Answer 1

a) 36:9+3=4+3=7=49

b) 64-27-8=37-8=29=841

c) 8x9:36+9=72:36+9=2+9=11=121

d) 16-8=8=64

e) 81-64+1=17+1=18=324

f) 9x64:36-1=576:36-1=16-1=15=225

Answer 2

6²:3²=(6:3)² = 2² = 4

4³-3³-2³ = (4×4×4)-(3×3×3)-(2×2×2) = 64-27-8 = 37-8 = 29

2³×3²:6²+3²= (2×2×2)×(3×3)×(6×6)+(3×3) = 8×9:36+9 = 72:36+9 = 2+9 = 11

2⁴-2³= (2×2×2×2)-(2×2×2)=16-8=8

3⁴-4³+3⁰= (3×3×3×3)-(4×4×4)+1=81-64+1=17+1=18

3²×4³:36-1= (3×3)×(4×4×4):36-1 = 9×64:36-1=576:36-1=16-1=15
