Question

Simplify the expression using exponent rules. Write the answer in scientific notation.

(6x10⁷)(8x10⁶)(9x10⁸)

Answer 1

= 6x8x9 x 10^(7+8+6)

= 432 x 10^21

= 432/10^2 x 10^21 x 10^2

= 4.32 x 10^23

Answer 2

This breaks down into (6x8x9) x (10⁶x10⁷x10⁸).

= (432) x 10^(6+7+8) = 432 x 10²¹ = 4.32 x 10²³
