WebFeb 28, 2024 · logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8. In the same fashion, since 102 = 100, then 2 = log10 100. … Make the base on both sides of the equation the SAME so that if bM=bN\large{b^{\color{blue}M}} = {b^{\color{red}N}}bM=bN then M=N{\color{blue}M} = {\color{red}N}M=N 1. In other words, if you can express the exponential equations to have the same base on both sides, then it is okay to set their … See more 1) Zero Property 2) Negative Exponent Property 3) Product Rule 4) Quotient Rule 5) Power to a Power Rule Let’s take a look at some examples!

Webthe answer is -2, 4 is 2^2 and 25=5^2 so 4/25 is the inverse of (5/2)^2 so its (5/2)^-2. to solve this you either have to just see how -2 would make everything line up, or plug it into a calculator with logs and then when the calculator says -2 justify why its exactly -2. WebTo solve for x x, we must first isolate the exponential part. To do this, divide both sides by 5 5 as shown below. We do not multiply the 5 5 and the 2 2 as this goes against the order of …
