Explanation

To solve the problem of finding the product of \(1.7 \times 10^4\) and \(12.5 \times 10^{-6}\) and expressing it in the standard form \(k \times 10^n\), we proceed as follows: 1. Calculate the Product: \[ (1.7 \times 10^4) \times (12.5 \times 10^{-6}) = 1.7 \times 12.5 \times 10^{4 + (-6)} \] \[ = 1.7 \times 12.5 \times 10^{-2} \] 2. Multiply the Decimal Numbers: \[ 1.7 \times 12.5 = 21.25тАжRead More
