Question

In standard form, which expression represents the following?

2×1,000+9×100+5×1+1×1100+3×11,000

A) 201,503
B) 101,503
C) 1,015,300
D) 150,103

Answer 1

The standard form of the expression 2×1,000 + 9×100 + 5×1 + 1×1100 + 3×11,000 is 2,905.103, which aligns with choice B) 2,905.103.

Step-by-step explanation:

In standard form, the expression that represents 2×1,000 + 9×100 + 5×1 + 1×1100 + 3×11,000 is An established way to approach this is to break down each term individually, respecting the base and exponent for each part of the expression and then combine them for the final answer:

• 2×1,000 = 2,000
• 9×100 = 900
• 5×1 = 5
• 1×1100 = 0.1 (since 1/100 = 0.01)
• 3×11,000 = 0.003 (since 1/1,000 = 0.001)

Adding these values together, we get:

2,000 + 900 + 5 + 0.1 + 0.003 = 2,905.103

Therefore, in standard form, the expression is:

B) 2,905.103
