| (a) \[15x{{y}^{2}},17y{{z}^{2}}\] |
| (b) \[-5{{a}^{2}}bc,11ab,13ab{{c}^{2}}\] |
Answer:
(a) \[~15x{{y}^{2}}\times 17y{{z}^{2}}=\left( 15\times 17 \right)\times x\text{ }\times \text{ }{{\text{y}}^{2}}\text{ }\times y\times {{z}^{2}}\] \[=255\,x{{y}^{3}}{{z}^{2}}\] (b) \[-5{{a}^{2}}bc\times 11ab\times 13ab{{c}^{2}}=(-5\times 11\times 13){{a}^{2}}bc\times ab\times ab{{c}^{2}}\] \[=-715\,{{a}^{4}}{{b}^{3}}{{c}^{3}}\]
