Question

Convert into scientific notation.

1.) 0.0000075
2.) 172000000​

Answer 1

Answer:

1)7.5 × 10-6

2)1.72 × 108

Step-by-step explanation:

1)Move the decimal 6 times to right in the number so that the resulting number, m = 7.5, is greater than or equal to 1 but less than 10

Since we moved the decimal to the right the exponent n is negative

n = -6

Write in the scientific notation form, m × 10n

= 7.5 × 10-6

2)Move the decimal 8 times to left in the number so that the resulting number, m = 1.72, is greater than or equal to 1 but less than 10

Since we moved the decimal to the left the exponent n is positive

n = 8

Write in the scientific notation form, m × 10n

= 1.72 × 108
