Answer:
Yes, it is harder.
Step-by-step explanation:
Answer:
Below in bold.
Step-by-step explanation:
c) 3 x (9^2)^3/4 x ((81^3)^5/6
= 3 x 81^3/4 x 81^15/6
= 3 x 81^(3/4 + 15/6)
= 3 x 81^13/4
= 3 x 3^13
= 3^14
= 4,782,969.
f) (5x^-1y^2)^-2 / (25 x^2 y - 1)^2
= 5^-2 x^2y^-4 / 625 x^4y^-2
= 5^-2 x^-2 y^-2 / 5^4
= 5^-6 x^-2y^-2
= 0.000064x^-2y^-2.
awnser: 42
step by step:
1. find the racio of both
2.multiply the awnsers by 7
3.finally subtract
Pretty sure it’s “b= p/2 - a” which is the second answer
You were using it for 6 hours because 70-25 is 45 and if you divide 7.50 and hour and 45 it’s 6
