(X⁸+x⁴+1) Answer

${\huge{\bf{\purple{\mathbb{\underline {Solutions}}}}}}$

(x²+X+1)(x²-x+1)(X⁴-x²+1)

(x⁴-x³+x²+x³-x²+x+x² -x+1) (X⁴-x²+1)

(x⁴+x²+1)(X⁴-x²+1)

(X⁸+x⁴+1) Answer

${\huge{\bf{\purple{\mathbb{\underline {Extra \: information}}}}}}$

For any two real numbers a and b, a, b ≠ 0, and for any two positive integers, m and n

➲ If a be any non - zero rational number, then

a^0 = 1

➲ If a be any non - zero rational number and m,n be integer, then

(a^m)^n = a^mn

➲ If a be any non - zero rational number and m be any positive integer, then

a^-m = 1/a^m

➲ If a/b is a rational number and m is a positive integer, then

(a/b)^m = a^m/b^m

➲ For any Integers m and n and any rational number a, a ≠ 0

a^m × a^n = a^m+n

➲ For any Integers m and n for non - zero rational number a,

a^m ÷ a^n = a^m-n

➲ If a and b are non - zero rational numbers and m is any integer, then

(a+b)^m = a^m × b^m

Answer 2

Step-by-step explanation:

प्रश्न:—

• x² + x + 1 , x² - x + 1 और x⁴- x² + 1 का गुणनफल ज्ञात कीजिए।

ज्ञात करना है:—

• गुणनफल ज्ञात कीजिए।

हल:—

x² + x + 1

x² + x + 1

x⁴ + x³ + x²

- x³ - x² - x

+ x² + x +1

x⁴ + x² + 1. = x⁴ + x² + 1

फिर, x⁴ + x² + 1

x⁴ - x² + 1

x⁸ + x⁶ + x⁴

- x⁶ - x⁴ - x²

+ x⁴ + x² + 1

x⁸ + x⁴ + 1

∴ अभीष्ट गुणनफल = x⁸ + x⁴ + 1
