How to solve for x in the exponent
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 = 48. Now, we can solve for x x by converting the equation to ... WebOne problem is is in step 4, you cannot factor out things using multiplication, factoring out is used with adding terms.

WebStep-by-step solution. Solving quadratic equations by completing the square. 1. Move all terms to the left side of the equation. Subtract -2 from both sides: Simplify the expression. 2. Find the coefficients. To find the coefficients, use the standard form of a quadratic equation: WebMar 25, 2024 · Article Summary X. To add exponents, start by solving the first exponential expression in the problem by multiplying the base number by itself the number of times shown in the exponent. For example, to solve for 3 to the fourth power, you would multiply 3 by 3 by 3 by 3 to get 81. Then, solve the second expression in the same way.
WebStart by factoring the base values to get a common base for the exponents. 9=3^2. Thus, 9^m = (3^2)^m = 3^ (2m) 81=3^4. Now your equation can be written as: 3^ (2m-1)*3^ (2m)=3^4. The left side can be simplified further by using properties of exponents: to multiply values with a common base, we add the exponents. 3^ (2m-1+2m)=3^4. 3^ (4m …
