2. Expand log 385.10 |
|
Answer» We first get the prime factors of 385. 385 = 5 × 7 × 11 Using the logarithmic formula to represent this in logarithm form. Formula : ㏒ₐᵇ = naⁿ= ba = the base, b=number, n = power In this case the powers are 5, 7 and 11 ㏒₁₀x = 5x = 10⁵㏒₁₀y = 7y = 10⁷㏒₁₀z= 11z = 10¹¹ Writing this in logarithm. ㏒₁₀10⁵+ ㏒₁₀10⁷+ ㏒₁₀10¹¹This is the expansion of ㏒ 10 to the power of 385. |
