Which of the following is equivalent to (1/2)^-2t

Zepler [3.9K]

Answer:

Choice (3) $\left(2^2\right)^t$ is correct.

Step-by-step explanation:

Given expression is $\left(\frac{1}{2}\right)^{-2t}$

Now we need to simplify this and check which of the given choices best match with it.

$\left(\frac{1}{2}\right)^{-2t}$

$=\left(\frac{1}{2^1}\right)^{-2t}$

$=\left(2^{-1}\right)^{-2t}$ {using formula $=\frac{1}{x^m}=x^{-m}$ }

$=\left(2^{-1}\right)^{-2t}$ {using formula $=\left(x^m\right)^n=x^{\left(m\cdot n\right)}$ }

$=2^{\left(-1\right)\left(-2t\right)}$

$=2^{2t}$

$=\left(2^2\right)^t$ {using formula $=\left(x^m\right)^n=x^{\left(m\cdot n\right)}$ }

Hence choice (3) $\left(2^2\right)^t$ is correct.
