$(600 \times 8 \times 75 \times 40) = 14,400,000$
General equation $= a \times b \times c \times d$ 1. Multiply the first two numbers together $(a \times b)$ $600 \times 8 = 4800$ New Equation $= (4800 \times 75 \times 40)$ 2. Multiply the next two numbers together $((a \times b) \times c)$ $4800 \times 75 = 360,000$ New Equation $= (360,000 \times 40)$ 3. Multiply the last two numbers together $(((a \times b) \times c) \times d)$ $360,000 \times 40 = 14,400,000$ Therefore, $(600 \times 8 \times 75 \times 40) = 14,400,000$
