Question 1 Report

Find the value of (0.006)3 + (0.004)3 in standard form
Answer Details
To solve this problem, we simply need to evaluate the expressions inside the parentheses first, then add the two results. (0.006)3 = 0.000000216, which can be written in standard form as 2.16 x 10-7. (0.004)3 = 0.000000064, which can be written in standard form as 6.4 x 10-8. Adding these two values gives: 2.16 x 10-7 + 6.4 x 10-8 = 2.76 x 10-7 Therefore, the answer is 2.8 x 10-7.
