${\huge{\rm{\underline{\underline{Question:-}}}}}$

Find the product:- (1)$-6a^2 × 5a^7$(2)$-8y^9 × -4y^3$

${\huge{\rm{\underline{\underline{Answer:-}}}}}$

★ 1) $-6a^2 × 5a^7$

★ Steps to follow:-

➪ Multiply the coefficient or the number near the respective exponent.

➪ Then, Multiply the exponents.

➪ Make sure that you know the law of exponents, mainly.......

$a^m × b^n = ab^{(m+n)}$

★ Solution:-

1) $-6a^2 × 5a^7$

$-30a^{(2+7)}($

$-30a^9$

★(2)$-8y^9 × -4y^3$

Steps to follow:-

➪ Multiply the coefficient or the number near the respective exponent.

➪ Then, Multiply the exponents.

➪ Make sure that you know the law of exponents, mainly.......

$a^m × b^n = ab^{(m+n)}$

★ Solution:-

★(2)$-8y^9 × -4y^3$

$32y^{(9+3)}$

$32y^{12}$

Answer 2

1) -6a² x 5a⁷ = -30a⁹

2) -8y⁹ x -4y³ = 32y¹²

Thnx ✌️✌️
