Question

Can u explain me pls i need it fast i will make it the brainliest answer

Answer 1

Step-by-step explanation:

first we change 121 to 11 square, which is in the brackets

then it becomes 11^2 × -2, which is equal to 11^ -4

then we change root 4 into a power by bringing it on the other side, writing it as 1/4 (one upon four)

after that u cut both the 4s which is written above 11 as powers

then u finally get 11^ -1 which is also written as 1/11

I hope u understand

Answer 2

Answer:

  $\frac{1}{11}$

Step-by-step explanation:

$\sqrt[4]{(121)^{-2} }$

$= \sqrt[4]{((11)^{2} )^{-2} }$     $(121 = 11^{2} )$

$= \sqrt[4]{(11)^{-2*2} }$      $((x^{a}))^{b} = x^{(a * b)}$

$= \sqrt[4]{(11)^{-4} }$          $(\sqrt[n]{x} = x^{\frac{1}{n} })$

$= 11^{(\frac{-4}{4}) }$

$= 11^{-1}$

$= \frac{1}{11}$
