Solution:
0.3 × 2.7
Using Distributive property of multiplication with respect to subtraction the value of multiplication of two rationals or two decimals
⇒0.3 × (3-0.3)
⇒ 0.3 × 3 - 0.3 × 0.3
⇒ 0.9 - 0.09
= 0.81
H C F of 0.3 and 2.7 is 0.3.
The Equivalent of product of 0.3 × 2.7 are
1.→0.9 × 0.9
2.→→ 3 × 0.27

Answer:
x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.
Step-by-step explanation:
(x3 + 2x - 1) (x4 - x3 + 3)
= x^7 - x^6 + 3x^3 + 2x^6 - 2x^4 + 6x - x^4 + x^3 - 3
= x^7 + x^6 - 3x^4 + 4x^3 + 6x - 3.
