$2^{\left(x+1\right)}+2^x+2^{\left(x-1\right)}=112$
Learn how to solve problems step by step online. Find the roots of 2^(x+1)+2^x2^(x-1)=112. Find the roots of the equation using the Quadratic Formula. Apply the property of the product of two powers of the same base in reverse: a^{m+n}=a^m\cdot a^n. Combining like terms 2\cdot 2^x and 2^x. Applying the property of exponents, \displaystyle a^{-n}=\frac{1}{a^n}, where n is a number.
