Question

Multiply or divide, write your answer in scientific notation.

(1.5×10^8)(5.9×10^4) =

Can you help me with this problem?​

Answer 1

(1.5 • 10^8)(5.9 • 10^4)

1.5 • 5.9 = 8.85

10^8 • 10^4 = 10^12

= 8.85 • 10^12 (the answer)

Answer 2

Answer:

$(1.5 \times {10}^{8} )(5.9 \times {10}^{4} ) \\ = 1.5 \times 5.9 \times {10}^{(8 + 4)} \\ = \boxed{8.85 \times {10}^{12}}$

8.85×10¹² is the right answer.
