Answer:

Step-by-step explanation:
We have to use the law of indices for finding the equivalent expression.
We square 8, which is 64 and multiply the two powers.
We multiply the 2 powers giving us,
, which simplifies to 2.
×
=
This is the answer as we multiply the two indices together.

Answer:
B. 1010
Step-by-step explanation:
<u>Simplify:</u>
<u>Note that:</u>
- ab = 10a +b
- ab0 = 10* (10a + b) = 10ab
- ab0ab = 1000ab + ab = 1001 ab
<u>Therefore:</u>
- (ab0+ab0ab) ÷ (ab) - 1 =
- (10ab + 1001ab) ÷ (ab) - 1 =
- (1011ab) ÷ (ab) - 1 =
- 1011 - 1=
- 1010
<u>Correct choice is</u> B.1010
Answer:
x = 93
Step-by-step explanation:
The measure of a straight line is 180°. So,
