Question

Find the value of $(5^5\times 3^5)+(5^0\times 3^0)$.

• A. ${15}^5+2$
• B. ${15}^5+1$
• C. ${15}^5$
• D. None of these

Answer 1

The correct option is B ${15}^5+1$

By the Laws of Exponents, we know that $a^m\times b^m=(ab{)}^m$ and $a^0=1$,
$\therefore (5^5\times 3^5)+(5^0\times 3^0)={15}^5+1$
