How do i solve the scientific notation?

for example if you gave 2x ten to the power of 3, that is scientific notation. So if you take it out of scientific notation you hwv3 2000.

Step-by-step explanation:

3 is amount of times you move to decimal to the right. So there is an invisible decimal after 2 so that gives you 2.0 So you take that decimal point and move it to the right three times. then you have 2000. but if you had 2× 10 to the power of 4, you would move the decimal to the right 4 times.

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
