Select the problems which show the correct answers. (1.12 x 105) (6.06 x 105) 6.79 x 1010 (2 x 101)(3.0 x 101) 6.0 x 101 (2.775 x 10−4) (4.775 x 104) 1.325 x 100 5 8.14 x 102 6.14 x 10−3

Step-by-step explanation:

To solve this problem we must solve all 4 operations.

For the first one we have:

When we have multiplication of powers of equal base (10) the same base is placed and the exponents are added

So:

Therefore the answer to this question is correct.

For the second question we have:

Then following the same procedure as in the previous question we have:

Then the answer shown in the statement is not correct, because 10 must be squared, product of the sum of its exponents (1 + 1)

For the third question we have:

Then it is verified that the answer for this operation is no correct

Finally, for the fourth question we have:

This we can write it as:

In division of powers of equal base (10 in this case) the same base is placed and the exponents are subtracted:

Finally, the problems that show correct answers are:

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
