Question

simplify. express your answer as a single term, without a denominator. $d \cdot d^9$

Explanation:

Step1: Recall exponent product rule

For same base $a$, $a^m \cdot a^n = a^{m+n}$

Step2: Identify values

Here, $a=d$, $m=1$, $n=3$

Step3: Apply the rule

$d^1 \cdot d^3 = d^{1+3} = d^4$

Answer:

$d^4$
