Question

find the product:- (-3/5 a^2b) × (-15/21 ab^2) ×(-1/5ab)​

Answer 1

Answer:

-3/35  )$a^{4}$$b^{4}$

Step-by-step explanation:

(-3/5a²b)⋅(−-15/21 ab² )⋅(−1/5 ab)

To multiply powers of the same base, add their exponents. Add 2 and 1 to get 3.

-3/5a³ b(−15/21 )b² (−-1/5 )ab

To multiply powers of the same base, add their exponents. Add 3 and 1 to get 4.

-(3/5)$a^{4}$b(−15/21)b² (−1/5 )b

To multiply powers of the same base, add their exponents. Add 1 and 2 to get 3.

(-3/5)$a^{4}$b³ (−15/21)(−1/5)b

To multiply powers of the same base, add their exponents. Add 3 and 1 to get 4.

-5/3)$a^{4}$$b^{4}$ (−15/21) (-1/5)

Reduce the fraction 15/21 to lowest terms by extracting and canceling out 3.

-3/5))$a^{4}$ $b^{4}$  (−5/7) (−1/5)

Multiply −3/5  and −  5/7   to get   3/7

(3/7)$a^{4}$ $b^{4}$ (−1/5)

Multiply  3/7  and −  1/5 to get −  3/35

-3/35  )$a^{4}$$b^{4}$
