What is the value of the expression simplified in Standard Notation: (3.2×10−2)(4.2×106)(5.2×105)

The value of the expression simplified in Standard Notation is:

(3.2×10^(-2))(4.2×10^6)(5.2×10^5)

To simplify this expression, we can multiply the coefficients and add the exponents separately.

(3.2 × 4.2 × 5.2) × (10^(-2) × 10^6 × 10^5)
= 70.656 × 10^(9)

Therefore, the simplified expression in standard notation is:

70.656 × 10^9
