Question

simplify. express your answer using positive exponents. $5s^{7}t^{7} \cdot 5st$

Explanation:

Step1: Multiply the coefficients

$5 \times 5 = 25$

Step2: Combine $s$ terms (add exponents)

$s^7 \times s^1 = s^{7+1} = s^8$

Step3: Combine $t$ terms (add exponents)

$t^7 \times t^1 = t^{7+1} = t^8$

Step4: Multiply all simplified parts

$25 \times s^8 \times t^8$

Answer:

$25s^8t^8$
