Question

Please help meeee ………..

Answer 1

x = 5

Explanation:

The equality of bases property says powers of the same base will be equal if and only if the powers are equal. This property is used to solve exponential equations.

Application

`((2)^x)/(2)=16\qquad\text{copy of the original equation}\\\\2*((2)^x)/(2)=2*16\qquad\text{multiply by 2 to isolate the base}\\\\2^x=32\qquad\text{simplify}\\\\2^x=2^5\qquad\text{rewrite the constant as a power of 2}\\\\\boxed{x=5}\qquad\text{use the Equality of Bases Property}`

Additional comment

Equating the exponents is fully equivalent to taking the logarithm of both sides of the equation, to that base.

`\log_2(2^x)=\log_2(2^5)\ \Longrightarrow\ x=5`
