Question

please give me the answer with exponents

Answer 1

$hii.. \\ \\ = > 1 + {2}^{ - 1} + {3}^{ - 1} + {4}^{0} \\ \\ = > 1 + \frac{1}{2} + \frac{1}{3} + 1 \\ \\ now \: by \: taking \: lcm \: .. \\ = > \frac{6 + 3 + 2 + 6}{6} = \frac{17}{6} \: ans \\ \\ hope \: this \: helps :)$

Answer 2

$\bf \large \it \: Hey \: User!!! \:$

given :- 1 + 2^-1 + 3^-1 + 4^0

some laws of exponent used here :-

>> (a/b)^-n = (b/a)^n

= 1 + 1/2 + 1/3 + 1

lcm of 1, 2 and 3 = 1 × 2 × 3 = 6

= 6/6 + 3/6 + 2/6 + 6/6

= ( 6 + 3 + 2 + 6 ) / 6

= 17/6
