Răspuns:

Explicație pas cu pas:

√(2²²-2^21 +2^18)=√2^18 ×√(2^4-2^3+1)=2^9 ×√(16-8+1)=512×3=1536

√(3^19- 3^16 -3^16)=√3^16 ×√(3³-1-1)=3^8 ×√25=6561×5=32805

√(2^30+ 2^29+ 2^26)=√2^26 ×√(2^4 +2³+1)=2^13×√25=40960

√(2²³-2²²+2^19)=√2^18 ×√(2^5 -2^4 +2)=2^9 ×√18=512×3√2=1526√2

√(3^20 -2×3^17)=√3^16 ×√(3^4 -2×3)=3^8×√75=6561×5√3=32805√3

√(2^29 +2^28 +2^25)=√2^24 ×√(2^5 +2^4 +2)=2^12 ×√50=4096×5√2=20480√2
