计算:√2a·√3a·√6a^4√125+ 5√1/45 +1/4√3.2 -3√0.2√2a·√3a·√6a^4
计算:√2a·√3a·√6a^4
√125+ 5√1/45 +1/4√3.2 -3√0.2
√2a·√3a·√6a^4

计算:√2a·√3a·√6a^4√125+ 5√1/45 +1/4√3.2 -3√0.2√2a·√3a·√6a^4
√2a×√3a×√6a^4
=√(2a×3a×6a^4)
=√(6²a^6)
=6a³
√125+5√1/45+1/4√3.2-3√0.2
=5√5+5√(5/225)+1/4√(16/5)-3√(1/5)
=5√5+5×(√5)/15+1/4×4/(√5)-3√(5/25)
=5√5+(√5)/3+1/(√5)-(3√5)/5
=5√5+(√5)/3+(√5)/5-(3√5)/5
=(75√5+5√5+3√5-9√5)/15
=(74√5)/15
