Question

simplify. express your answer using positive exponents. 10c^6·7c^9

Explanation:

Step1: Multiply coefficients

Multiply 10 and 7: $10\times7 = 70$.

Step2: Use exponent - rule for same - base

For $c^6\times c^9$, by the rule $a^m\times a^n=a^{m + n}$, we have $c^{6+9}=c^{15}$.

Step3: Combine results

The result is $70c^{15}$.

Answer:

$70c^{15}$
