Final answer:
To find the number that is 10⁵ more than the expression (4×10⁴) (3×10³) (2×10²) (1×10), we first add together the products of each term and then add 100,000. The sum is 143,210, making the correct answer (c) 143,210.
Step-by-step explanation:
To determine which number is 10⁵ more than the given expression (4×10⁴) (3×10³) (2×10²) (1×10), we first need to multiply the terms in the expression together. When we multiply powers of 10 together, we add the exponents. Therefore, the given expression is equivalent to:
4×10⁴ = 4 × 10,000 = 40,000
3×10³ = 3 × 1,000 = 3,000
2×10² = 2 × 100 = 200
1×10¹ = 1 × 10 = 10
Adding these together:
40,000 + 3,000 + 200 + 10 = 43,210
Now, we add 10⁵ (which is 100,000) to this sum:
43,210 + 100,000 = 143,210
The number that is 10⁵ more than the initial expression is 143,210, which corresponds to answer choice (c) 143,210.
