WebFeb 14, 2016 · 59. To evaluate log8128, let log8128 = x Then by definition of the logarithm, 8x = 128 Since 8 = 23 and 128 = 27, we obtain (23)x = 27 23x = 27 If two exponentials with the same base are equal, then their exponents must be equal. Hence, 3x = 7 x = 7 3. Check: If x = 7 3, then 8x = 87 3 = (81 3)7 = 27 = 128. Share. WebExpert Answer. 1st step. All steps. Final answer. Step 1/1.

WebNov 11, 2024 · It's critical to combine similar phrases using logarithm principles while examining a log equation. These standards define the structure for performing a sequence of within log operations. You may combine the first two terms using the log rules and by using the equation: log7.1(X - 1) + log7.1(3) = log7.1(X + 1) This results in: WebNotice that the numerator and the denominator on the RHS are both square numbers. Also notice that you see 5 on the LHS and 5² on the RHS. So maybe x=2. But (5/2) 2=25/4. The problem is that the numerator and denominator are the wrong way around. So raise both sides to the power of -1. That gives (5/2)-2=4/25, so x=-2. WebApr 10, 2024 · If possible, use Rules of Exponents to write the equation in the form a = bp ( x) .
