Question

(3x10^3)^4 + (3x10^5)^3​

Answer 1

Solución:

(3x10³)⁴ + (3x10⁵)³

(3 × 10³x)⁴ + (3x × 10⁵)³

(3 × 10³x)⁴ + (3 × 10⁵x)³

10³ = 10 × 10 × 10 = 1000

10⁵ = 10 × 10 × 10 × 10 × 10 = 100000

(3 × 1000x)⁴ + (3 × 100000x)³

3 × 1000x = 3000

3 × 100000x = 300000

(3000x)⁴ + (300000x)³

= 3000⁴x⁴ + 300000³x³
