Question

B=121-[2^4-(4^2+889)

Answer 1

\(B=121-\left[2^4-\left(4^2+889\right)\right]\)

\(\Rightarrow B=121-2^4+\left(4^2+889\right)\)

\(\Rightarrow B=121-2^4+4^2+889\)

\(\Rightarrow B=121-16+16+889\)

\(\Rightarrow B=121+889\)

\(\Rightarrow B=1010\)

Answer 2

\(B=121-\left[2^4-\left(4^2+889\right)\right]\)

\(\Rightarrow B=121-2^4+\left(4^2+889\right)\)

\(\Rightarrow B=121-2^4+4^2+889\)

\(\Rightarrow B=121-16+16+889\)

\(\Rightarrow B=121+889\)

\(\Rightarrow B=1010\)
