Question

Solve for x: 10²ˣ⁺³ = 94

Answer 1

Answer:

Solution:-

(106)³ - (94)³

(100+6)³ - (90 + 4)³

(100 + 6)³ = (100)³ + 3 × (100)² × 6 + 3 × 100 × (6²) + (6)³ [By using the identity (x+y)³ = x³+3x²y+3xy²+y³]

= 1191016

(90 + 4)³ = (90)³ + 3 × (90)² × 4 + 3 × 90 × (4)² + (4)³ [By using the same identity] = 830584

1191016 - 830584

= 360432  Answer.
