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

Question

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


`(( (1)/(2)) ^(2) ))\ x^(t)`

`(1 ^(t) )/(2 ^(2) )`

`(2 ^(2) ) ^(t)`

`2 ^(2) * 2^(t)`

Answer 1

`\bf \left( \cfrac{1}{2} \right)^(-2t)\implies \left( \cfrac{2}{1} \right)^(2t)\implies (2)^(2t)\implies 2^(2\cdot t)\implies (2^2)^t`
