1. Expands the following indices and calculate the answers, example 2 2 = 2 x 2 = 4 a. 2 5
b. 3 3
c. 10 3
d. 1 4
e. 5 3

2. Contract and write the following expansions to index form., example 2 x 2 x 2 = 2 3
a. 2 x 2 x 2 x 2 =
b. 4 x 4 =
c. 10 x 10 x 10 x4 x 4 x 4x 4 =
d. 3 x 3 x 3 x 3 x 3 x 3 x 3=
e. 5 x 5 x 5 x 3 x 3=

11

step-by-step explanation:

32.50-7.50=25

225/25=11

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

total amount of money that he should pay if he has not used his duty free exemption is $98

step-by-step explanation:

given a united states citizen returning to the states declares the following items at the customs office: 3 shirts at $8.50 each 2 dresses at $27.50 each 1 pair of gold cuff links at $17.50 per pair. we have to find how much he pay

cost of 3 shirts if one cost at $8.50 is

cost of 2 dresses if one cost at $27.50 is  

cost of 1 pair of gold cuff at $17.50

so, total amount of money that he should pay if he has not used his duty free exemption is   $25.5+$55+$17.50=$98
