f. 10.
g. 4.5 x 10^2
h. 1.2

these are my answers could someone check them for me

Those look ok to me.

To report the given numbers to two significant figures, you need to understand the concept of significant figures. Significant figures are the digits in a number that carry meaning in terms of precision or accuracy.

Here's how to report each number to two significant figures:

a. 3.1459:
Since there are five significant figures, we round it to two significant figures. The answer is 3.1.

b. 6.003:
Since there are four significant figures, we round it to two significant figures. The answer is 6.0.

c. 42:
The number 42 already has two significant figures, so no rounding is necessary.

d. 6.0233 x 10^23:
In scientific notation, the significant figures are in the coefficient (6.0233). We round it to two significant figures by ignoring the decimal places. The answer is 6.0 x 10^23.

e. 14.456 + 3.87:
First, add the two numbers: 14.456 + 3.87 = 18.326.
Since both numbers have four significant figures, we report the sum to two significant figures. The answer is 18.

f. 9.9999995 - 0.0108:
First, subtract the two numbers: 9.9999995 - 0.0108 = 9.9891995.
Since the first number has eight significant figures and the second number has four significant figures, we report the difference to four significant figures. The answer is 9.989.

g. 67.3 x 6.667:
Multiply the two numbers: 67.3 x 6.667 = 448.8371.
Since both numbers have three significant figures, we report the product to three significant figures. The answer is 449.

h. 4.93 / 3.946:
Divide the two numbers: 4.93 / 3.946 = 1.2467955305241344.
Since the first number has three significant figures and the second number has four significant figures, we report the quotient to three significant figures. The answer is 1.25.
