Solve for x using logarithms

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 operations! \begin {aligned} 5\cdot 2^x&=240 \\\\ 2^x&=48 \end {aligned} 5 ⋅ 2x 2x = 240 … WebLearn how to solve differential calculus problems step by step online. Find the derivative using logarithmic differentiation method x^21/2x. Simplifying. To derive the function \frac{1}{2}x^{3}, use the method of logarithmic differentiation.

WebTo solve a logarithmic equations use the esxponents rules to isolate logarithmic expressions with the same base. Set the arguments equal to each other, solve the … 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. chill rentals maine https://mrrscientific.com
