Write the number in standard notation 2.99x10^-4

The number written in standard notation is 0.000299.

To write the number 2.99x10^-4 in standard notation, you can move the decimal point four places to the left, since the exponent is negative.

Thus, 2.99x10^-4 in standard notation is 0.000299.

To write the number 2.99x10^-4 in standard notation, we can follow these steps:

Step 1: Take the number before the multiplication sign, which is 2.99.

Step 2: Move the decimal point to the left or right to get a number between 1 and 10. In this case, we need to move the decimal point 4 places to the left because the power of 10 is negative.

2.99 becomes 0.000299.

Step 3: Multiply this number by 10 raised to the power of the exponent after the multiplication sign. In this case, it's 10^-4.

0.000299 x 10^-4 = 0.0000299

Therefore, the standard notation for 2.99x10^-4 is 0.0000299
