Look at the pic to see how to set up the proportion.
Answer:
Step-by-step explanation:
apply the indices law
- multiple means addition
- division means subtraction
- you are suppose to add the powers or subtract where necessary
- 4^9x 4^3= 4^5
- 6^5x6^2=6^7
- 8^6÷8=8^5
- 7^8÷7^6=7^2
A. x= 11/5
b. x= 6
c. x= -12/2
d. x= 6/5
A.
(64x<span>² + 96x + 36) / (16x + 12)
= 4(16x</span><span>² + 24x + 9) / 4(4x + 3)
= 4*(4x + 3)(4x + 3) / 4(4x + 3)
= 4x + 3
b.
1.79 x 10^5 = 1.79 * 100,000 = 179,000
c.
(5.9736 x 10^24) + (4.8685 x 10^24)
= (5.9736 + 4.8685) x 10^24
= 10.8421 x 10^24
= 1.08421 x 10^25</span>
Just plug in 2 for p. 3*2 - 2 = 6-2 = 4
