the answer is 11,600,000,000,000
Step-by-step explanation:
pemdas
(1.2 x 10 ^13) - (4 x 10 ^11)
10^13 = 10,000,000,000,000 put that in scientific notation to make it simpler do same for 10 ^11
10 x 10^13
(1.2 x 10 x 10^13) - ( 4 x 10 x 10^11)
now solve the first equasion
12,000,000,000,000 - 400,000,000,000
subtract
11,600,000,000,000
Answer: 10
Step-by-step explanation: Remember that squaring a number is multiplying a number by itself. 100 = 10² because 10 x 10 = 100.
The solution to the equation is x < 1.25
X*y=72
x = 5y-2
x=72/y
72/y=5y-2
72=5y^2-2y
5y^2 -2y - 72 = 0
(5y+18)(y-4)=0
y = -18/5 discard
or y = 4
4x=72
x=18
(18,4)
Answer:
3/2
Step-by-step explanation:
Apply exponent rule: a^-1 = 1/a
(2/3)^1 = 1/2/3
Apply the fraction rule: 1/a/c = c/b
3/2
