plz ans this wright answer i will mark brainlist ​ step by step

Answer 1

Answer:

$\frac{1}{531441}$

Step-by-step explanation:

$(3^6$÷$3^8)^4$ × $3^{-4}$

=($3^{-2}$)⁴  × $3^{-4}$

= $3^{-8}$ × $3^{-4}$

= $3^{-8-4}$

=$3^{-12}$

=$\frac{1}{3^{12}}$

=$\frac{1}{531441}$

Ans:-$\frac{1}{531441}$

Answer 2

Answer:

Step-by-step explanation:

Given that,

( 3⁶ ÷ 3⁸ )⁴ × 3^ - 4 (∵" ^ " this symbol means " to the power of " )

= ( 3⁶ × 1/3⁸ )⁴ × 3^- 4

= ( 3⁶ × 3^ - 8 )⁴ × 3^ - 4 ( ∵ 1/a ^m = a ^ - m )

= ( 3^(6+( - 8 ) )⁴ × 3^ - 4 (∵Bases are equal then powers should be add )

= ( 3^ 6 - 8 )⁴ × 3^ -4

= ( 3 ^ - 2 ) ⁴ × 3^ - 4

= 3^- 8 × 3^- 4

= 3 ^ ( -8-4) (∵Bases are equal then powers should be add )

= 3 ^ -12 ( or ) 1/ 3¹² is the answer.
