Answer 2

Let's simplify both expressions:

A) 7x⁴y³ × 7x⁴y³

To simplify this expression, you can use the properties of exponents. When you multiply two terms with the same base (in this case, both terms have a base of 7 and the same variables x and y), you can add the exponents:

(7x⁴y³) × (7x⁴y³) = 7^(1+1) x^(4+4) y^(3+3) = 7^2 x^8 y^6

So, A simplifies to:

49x^8y^6

B) 1.12x⁶y² × 25/7xy³z²

To simplify this expression, first, multiply the numerical constants:

1.12 × 25/7 = 28/7 = 4

Now, multiply the variables with the same base (x, y, and z) by adding their exponents:

x⁶y² × xy³z² = x^(6+1) y^(2+3) z² = x^7y^5z²

So, B simplifies to:

4x^7y^5z²
