Question

Complete the following equation,


44 − 33+ 22 − 11=4^4 \ − \ 3^3 + \ 2^2 \ − \ 1^1=

Worked Solution

44 − 33+ 22 − 114^4 \ − \ 3^3 + \ 2^2 \ − \ 1^1
= (4×4×4×4) − (3×3×3)+(2×2) − 1(4 \times 4 \times 4 \times 4) \ − \ (3 \times 3 \times 3)+(2 \times 2) \ − \ 1
= 256 − 27+4 − 1256 \ − \ 27 + 4 \ − \ 1
