Answer 1

Answer:

$50 {a}^{8} {b}^{7} {c}^{9}$

Step-by-step explanation:

$(2 {a}^{2} {b}^{2} )(5a {b}^{4} {c}^{2} )(5 {a}^{5} b {c}^{7} ) = \\ = (2 \times 5 \times 5)( {a}^{2} \times a \times {a}^{5} )( {b}^{2} \times {b}^{4} \times b)( {c}^{2} \times {c}^{7} ) \\ = 50 \times {a}^{2 + 1 + 5} \times {b}^{2 + 4 + 1} \times {c}^{2 + 7} \\ = 50 {a}^{8} {b}^{7} {c}^{9}$
