Exercise 1 Page 455

To multiply exponential numbers with the same base but different exponents, we add the exponents and keep the base the same.

$7 x^{10}$

Practice makes perfect

To multiply exponential numbers with the same base but different exponents, we add the exponents and keep the base the same.

a^{m} \cdot a^{n} = a^{m + n}

Keeping this in mind, let's simplify the given expression.

(x^{2}) (7 x^{8})

CommutativePropMult

Commutative Property of Multiplication

7 (x^{2} \cdot x^{8})

$a^{m} \cdot a^{n} = a^{m + n}$

7 (x^{2 + 8})

Add terms

7 (x^{10})

Remove parentheses

7 x^{10}
