1st Question :-
[tex] \sf \: 2 { a }^{ 2 } { b }^{ 3 } \times -3 { a }^{ 2 } b \times -5ab ^ { 2 }[/tex]
To multiply powers of the same base, add their exponents. Add 2 and 2 to get 4.
[tex] \sf \: 2a^{4}b^{3}\left(-3\right)b\left(-5\right)ab^{2} [/tex]
To multiply powers of the same base, add their exponents. Add 4 and 1 to get 5.
[tex] \sf \: 2a^{5}b^{3}\left(-3\right)b\left(-5\right)b^{2} [/tex]
To multiply powers of the same base, add their exponents. Add 3 and 1 to get 4.
[tex] \sf \: 2a^{5}b^{4}\left(-3\right)\left(-5\right)b^{2} [/tex]
To multiply powers of the same base, add their exponents. Add 4 and 2 to get 6.
[tex] \sf \: 2a^{5}b^{6}\left(-3\right)\left(-5\right) [/tex]
Multiply 2 and -3 to get -6.
[tex] \sf-6a^{5}b^{6}\left(-5\right) [/tex]
Multiply -6 and -5 to get 30.
[tex] \boxed{ \boxed{ \bf \: 30a^{5}b^{6} }}[/tex]
