(4⁵× x + 32²) × 2⁵=2¹⁶ × x
(1024x + 1024) × 32 = 65536 / ÷32
32x + 32 = 2048
x = 3

x/2⁵ + (¼)² + (-⅛)² × x + 1/2³= x/32 + 1/16 + 1/64x + 1/8= 2x + 4 + x + 8 = 3x + 12

x/4⁴ - 1/(-2)⁶ = -(-1/16)²
x/256 - 1/64 = -1/256 /×256
x - 4 = -1
x = 3

(4⁵× x + 32²) × 2⁵=2¹⁶ × x
(210× x + 210) × 2⁵=2¹⁶ × x
210(x+1) × 2⁵=2¹⁶ × x
215(x+1)= 2¹⁶ × x /:215
x+1=2
x=1
