NettetTo 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 operations! \begin {aligned} 5\cdot 2^x&=240 \\\\ 2^x&=48 \end {aligned} 5 ⋅ 2x 2x = 240 = 48. Now, we can solve for x x by converting the equation to ... NettetUse the like bases property to solve the equation: (1/3)^(n-7)=3^(6n-9) Answer provided by our tutors (1/3)^(n-7)=3^(6n-9) (3^(-1))^(n-7) = 3^(6n-9) 3^((-1)(n-7)) = 3 ...

To do this, we apply the change of base rule … theletter 攻略NettetThis means that logarithms have similar properties to exponents. Some important properties of logarithms are given here. First, the following properties are easy to prove. logb1 = 0 logbb = 1. For example, log51 = 0 since 50 = 1. And log55 = 1 since 51 = 5. Next, we have the inverse property. logb(bx) = x blogbx = x, x > 0. the letter z in russian

"NettetUsing Like Bases to Solve Exponential Equations. The first technique involves two functions with like bases. Recall that the one-to-one property of exponential functions tells us that, for any real numbers b, b, S, S, and T, T, where b > 0, b ≠ 1, b > 0, b ≠ 1, b S = b T b S = b T if and only if S = T. S = T. " - Like bases property logarithms

NettetWe have a similar property for logarithms, called the product rule for logarithms, which says that the logarithm of a product is equal to a sum of logarithms. Because logs are exponents and we multiply like bases, we can add the exponents. We will use the inverse property to derive the product rule below.
