Question

which of the following equations is true? \\( 1 + 1 = 1 cdot 1 \\) \\( 10 cdot 1 = 0 + 10 \\) \\( 2 cdot 1 cdot 0 = 2 + 1 + 0 \\) \\( 4 + 1 = 4 cdot 0 \\)

Explanation:

Step1: Evaluate Option 1

Left side: $1+1=2$, Right side: $1\cdot1=1$. $2
eq1$, so false.

Step2: Evaluate Option 2

Left side: $10\cdot1=10$, Right side: $0+10=10$. $10=10$, so true.

Step3: Evaluate Option 3

Left side: $2\cdot1\cdot0=0$, Right side: $2+1+0=3$. $0
eq3$, so false.

Step4: Evaluate Option 4

Left side: $4+1=5$, Right side: $4\cdot0=0$. $5
eq0$, so false.

Answer:

B. $10\cdot1 = 0+10$
