Question

(7.2×10−1)×(4×10−7) how do i solve this

Answer 1

Explanation:

To solve the expression (7.2×10^(-1))×(4×10^(-7)), you can multiply the numerical values and combine the exponents.

First, multiply the numerical values:

7.2 × 4 = 28.8

Next, add the exponents of 10:

10^(-1) × 10^(-7) = 10^(-1-7) = 10^(-8)

Putting it all together, the expression simplifies to:

28.8 × 10^(-8)

This is the final answer in scientific notation.
