The value of the expression in scientific notation is determined as 7.8 x 10¹³.

How to calculate the value of the expression?

The value of the expression in scientific notation is calculated as follows.

The given expression;

(5.2 x 10⁵) (1.5 x 10⁸)

We will multiply the numbers with decimals together and numbers with powers together.

= (5.2 x 10⁵) (1.5 x 10⁸)

= (5.2 x 1.5) x (10⁵ x 10⁸)

= (7.8) x (10⁵ ⁺ ⁸)

= 7.8 x 10¹³

Thus, we can conclude that the value of the expression in scientific notation is determined as 7.8 x 10¹³.
