A.238,300
B.23,830
C.2230
D.70

Answer 1

The value equivalent to 2.4 x 10⁴ - 1.7 x 10² is found by subtracting 170 from 24,000, which equals 23,830.

Step-by-step explanation:

To solve the expression 2.4 x 10⁴ - 1.7 x 10², we must first convert each term into standard numerical form by multiplying the coefficient by 10 to the power of the exponent. The first term, 2.4 x 10⁴ is equivalent to 24,000, and the second term, 1.7 x 10² is equivalent to 170. Now we subtract the smaller number from the larger number to get the result:

• 2.4 x 10⁴ = 2.4 x 10,000 = 24,000
• 1.7 x 10² = 1.7 x 100 = 170
• 24,000 - 170 = 23,830

Therefore, the value equivalent to 2.4 x 10⁴ - 1.7 x 10² is 23,830.
