Answer:
D, E &F
Step-by-step explanation:
Lets's go down the list and evaluate each choice
A. (3^8) / (3^4) = 3^ (8-4) = 3^4 (≠ 3^2)
B. 6²/2 = (2 x 3)²/2 = (2²·3²)/2 = 4·3²/2 = 2.3² (≠ 3^2)
C. (3^5) ·(3^3) = 3^ (5+3) = 3^8 (≠ 3^2)
D 3·3 = 3^2 (Answer)
E. (3^12) / (3^10) = 3^ (12 -10) = 3^2 (Answer)
F. (3^-3) / (3^-5) = 3^ [ -3 -(-5) ] = 3^ (-3 + 5) = 3^2 (Answer)
Answer:
140
Step-by-step explanation:
Since m∠2 is 40°, then the m∠1 is also 40°. With that, ∠1 and ∠5 are supplementary, so we have 180 - 40 = 140°
Answer:
976 421; 124 679
Step-by-step explanation:
Part A. Largest number
Leslie's number was 976 421.
This is because the largest numbers are in the positions of largest value.
For example, 9 in the hundred thousands place, the next largest number in the ten thousands place, and so on.
===============
Part B. Smallest number
The smallest possible number is 124 679.
The value of the 4 is greater than the value of the 6 because the 4 is in the thousands place and the 6 is only in the hundreds place.
4000 > 600.
