Question

1×2^-1 =0.5 how ?explain pls...
​

Answer 1

Because 2 ^-1 = ½ as when the exponential no. is negative of any number the no. is converted into fraction with numerator as 1

For example ;2^ -2 so it will be 1/ 2² or 1/4

Hence 1/2 =0.5

And multiplying by 1 there the number will be itself only

so 1 × 2^-1 =0.5

Answer 2

Step-by-step explanation:

$1×2^{-1} =0.5$

$L.H.S \: = 1 \times {2}^{ - 1}$

$= {2}^{ - 1}$

$= \frac{1}{2}$

$= 0.5$

$= RHS$
