a) √6×24+√3×12 = √144+√36 = 12+6 = 18
b) √760-31 + √1331-35 = √729 + √1296 = 27+36 = 63
c) √63+3×27 + √540+2×18= √63+81 + √540+36= √144 + √576= 12 +24 = 36
d) √399240+√32902+954 = √399240 +√33856 = √399240+184 = √399424 = 632
e) √646-5√7×28 + √468-6√18×32 =
√646-5√196 + √468-6√576 =
√646-5×14 + √468-6×24 =
√646-70 + √468-144 = √576 + √324 = 24 + 18 = 42
f) √947+√7√743+41 =
√947+√7×28 = √947+14 = √961 = 31
