Evaluate: 11 - 12 ÷ 12 × 8
3
Apply the BODMAS order of operations: division and multiplication first (left to right), then subtraction.
The trailing number in the printed stem appears OCR-damaged; the answer key of 3 corresponds to the intended last operand being 8, giving the expression \(11 - 12 \div 12 \times 8\).
Step 1: \(12 \div 12 = 1\).
Step 2: \(1 \times 8 = 8\).
Step 3: \(11 - 8 = 3\).
Hence, the value of the expression is 3.
Evaluate: (-37) + (-56) ÷ (-3) × 3
Find the total number of prime factors of the number \(5^8 \times 6^7 \times 11^4\).
If P = 0.3 × 0.3 + 0.03 × 0.03 - 0.6 × 0.03 and Q = 0.54, then \(\rm \frac{P}{Q}\) is equal to:
