If (q=2^5\times3^b\times5^2\times7) and (q=604800), what is the value of (b)?
Answer and explanation
Correct answer: 3
Step 1: Write (604800=6048\times100). Step 2: (6048=2^5\times3^3\times7) and (100=2^2\times5^2), so the actual form is (2^7\times3^3\times5^2\times7). Step 3: The given power of 2 does not match, but the power of 3 is (b=3).
