Final answer:
To simplify the expression (20+168)÷(1210)+3(2), add 20 and 168, divide by 1210 to get 3×105, then add the product of 3 times 2 which is 6, to obtain the final simplified expression.
Step-by-step explanation:
The question asks to simplify the expression (20+168)÷(1210)+3(2). To do this, we will perform the operations step by step. First, we add the numbers within the parentheses which gives us 20+168=188. Then we need to divide 188 by 1210. Recognizing that 188 is essentially 24×101, we can express 188 as 24×102.
The division by 1210 is now simplified to 24×102-7, resulting in 24×10-5 or 3×105. Next, we compute the multiplication by 3, which yields 3(2)=6. Finally, we add the results of these operations to arrive at our simplified expression, which is 3×105 + 6.
