Write the expression as a number in scientific notation.

the quantity 3.6 times ten to the fifth power end quantity times the quantity 1.5 times ten to the negative eighth power end quantity all divided by the quantity 2.5 times ten to the negative fourth power end quantity

a 2.6 × 107
b 2.16 × 101
c 2.16 × 10−1
d 2.6 × 10−7

To solve this expression, we need to multiply the numbers in the numerator and divide that product by the number in the denominator.

First, multiply 3.6 and 1.5:
3.6 * 1.5 = 5.4

Next, add the exponents of 10:
5 + (-8) = -3

Finally, divide 5.4 by 2.5:
5.4 / 2.5 = 2.16

Therefore, the expression in scientific notation is 2.16 × 10^(-3).
The correct answer is c) 2.16 × 10^(-1).
