Answer:
Please see the question below.
Step-by-step explanation:
In the expression "[4 x 3⁵ - 9 x (-7)]" I'm unclear if the "x" is a multiplication sign, or the variable x. I'll assume it is the variable x in my answer.
4 x 3⁵ = 972x
- 9 x (-7) = 63x
3³ (-4² +2²) = 27 (20) = 540
-11 = -11
========
Putting it all together:
972x + 63x + 540 -11
1035x + 529
1a) 8 / (1/2) = 16 * 3 = 48
1b) 3sqrt(49) = 3 * 7 = 21
1c) (5+2)(-8) / (-2)^3 -3
(7*-8) / (-8 -3)
-56/-11
56/11
0.15m+25=c
replace c with 71.50
the third one
25+0.15m=71.8
4 to 6
The bill = $190
Less flat fee = 25
Work done = $165
